HELP. i only have first gear my Transmission faild and left me stranded

[subodh]

for a long time my transmission has been slipping in 2 gear.

when i changed the oil it was like thick mud or grease in bottom of it alot of it

so i was waiting for somthing to go out.

and i noticed i couldnt get the truck to go forward in nothing but first gear and after that i couldnt get it to move in reverse.



its an auto so i think i also would need a torque converter



waht should i do where do i get most bang for the buck?

and i want a transmission i can race.



my mods are



mods

smarty tuner

deleted kitty

htb 62/12 (35psi / going to put up to 50 after new gasket and bolts)

flux 2 (100hp injectors)

fass 150gph

modded airbox

t&c cp3 stage1





ive been thinking about dtt (diy kit)

i live in finland so noone have really knowledge of these trucks here

who would sell me a trann chepes if i wanted a bolt on?`

or if i go with a diy kit...

dont really know

Those two requirements are going to cause you problems. They will conflict you for the term of your truck ownership. :-laf





If you want it cheap or moderate cost don't even THINK about racing, the results will be less than adequate.



If you really want to race resign yourself to about $6k USD for start. The old adage holds so very true here, pay to play.





Unless you are very familiar with thes eauto transmissions and understand how to beef them up, but one setup for what you want to do. There is a LOT that goes into building a transmisison that will even come close to standing up behind a Cummins in a race scenario.



Just a couple places to start talking with: Goerends, DTT, Garmons, ATS, Suncoast. Warranty is going to be non-existent and you wil have to work out costs when parts break or something goes wrong. Its not a matter of if, its a matter of when something will show up.



Good luck with your choice.

 

[subodh]

what parts do i need?

please help me and write down everything i need to change

to get it to hold up for playing around abit

im thinking of doing the build myself. .

the shipping from states to finland was 1200dollars

and then i had to pay the same for shipping my core back



parts woud be the best option but i dont know what to get

or from where to get it!?



i dont know what horsepower my truck puts out

but i have those mods and i maby will put one turbo more

so i get a compound setup later on and change headbolts + gasket. .

but thats it i will not do anything more to it

Yeah, the shipping takes all the fun out of getting a complete unit.



It is not so much how much power the truck makes as it is how you are going to use it that counts. You can run 600 HP thru a stock trans and not have issues. Try to run the TQ the 600 HP will generate thru the trans and it will just wimper and die.



You obviously will want a triple disk TC, billet input and out put shafts, upgraded disk counts in the clutch packs, billet servos, etc. Now, what ppieces you use to achieve the greater clutch counts and how you set the VB will determine if it will last racing and\or be a well mannered street driver. Racing type clutches hold power and load well but don't last as long. Milder clutches that work well in normal driving suffer under WOT and heavy TQ applications. Its a tradeoff at times to strike a balance and there are tricks to do that and understanding how far to push it will keep things happy.



My advice, call DTT and tell them what you want to do with the truck. They will give you a good idead what parts and mods are required, plus, they are pretty good at phone support to do the build. Just remeber you can thro all the high $$ parts you want into the trans, but, if it is not set up correctly it is no better than stock. Flip 1 thrust washer the wrong way and it will toast the trans in a hurry under heavy power.



Too bad nobody publishes an ATSG like manual with all the collected tricks and tips to build a high power trans, but, if it was that easy a lot of shops would be out of business.

i found out that dieseltrans had a kit that would cost me 3000dollars with shipping but got dissapointed with their suport... .



i found another place that has these (transmissioncenter.com)

#K48RZ2. Turn your 48RE Diesel transmission or 48RE Viper motor transmission into our level 4 Ramzilla transmission. This Combo Kit is for late 2003 up 48RE transmissions only. You get the Alto Red Eagle master rebuild kit, #1HE-48 plus 1 extra clutch and 1 extra steel, extreme duty brass impregnated carbon fiber flex band, Transgo 48RE Shift Kit, performance 3-4 accumulator spring, heavy duty Sonnax low / reverse servo, Sonnax heavy duty / no leak intermediate servo cover, full time torque converter fluid feed valve, heavy duty intermediate band apply strut, Sonnax 300M input shaft, 10 overdrive clutches, all extra clutches needed for the buildup - 2 forward clutches and 2 steels, 1 overdrive brake clutch and steel with thin backing plate, deep cast aluminum pan and one thin forward backing plate. The torque converter will be a full size triple clutch billet converter for V-10 gas or diesel. Save 9. 8% here. Kit with full size torque converter $2500. 00... WHO MAKES THEIR TQ???



have you guys heard about these companies and parts?



but tod @ tc diesel is looking for some parts and he has always been kind

and fast shipping so i probably go with his idea when he calls me back

i think his looking into goerend parts?

 

[subodh]

help me with this please and i will take alot of pictures an make a manual here. .

for the moment i have a atsg maual or it was really only some pictures. . i dont know if i can find somthing better or not? maby i check my ALLDATA

 

[cerberusiam]

Tranmissioncenter is PATC out of Bosier City La. They have most of the same parts and kits like th eother delaers only theirs are more mainstream and not diesel specific.



I think they build their own TC's but not sure.



All depends on how much you want to bite off.

 

[AWeaver]

you cant go wrong with goerend. search the threads on tdr. if i had the $$$ thats the transmission id buy. or if you cant afford the whole replacement, buy what you can from them. start with the tc and vb and go from there. i know their customer service is top notch.

 

[subodh]

got a partslist from dtt

do i need all this?

its getting out of my pricerange







$ 2295 DIY KIT



$ 745 INPUT SHAFT



$ 300 TC CORE CHARGE



$ 399 FLEXPLATE



$ 825 BILLET OUTPUT SHAFT



$ 95 governor solenoid



$ 225 wiring harness and transducer



total 4884... .



can take away anything?

on other hand to do this job twice isnt fun but i cant handel all right now

and i need to get the truck running

 

[TCDiesel]

Billet output... .

 

[cerberusiam]

Billet output shaft, flex plate for sure BUT don't think you are going to be able to race it or run it hard. The flex plate and billet output are going to put limits on how much power and how hard you can twist its tail.



Not sure what the $225 wiring harness and transdcuer is. If that is new solenoids and harness for the VB you could leave that off also.

wiring and transducer is in other terms gov pressure sensor with wires for it. .

 

[cerberusiam]

wiring and transducer is in other terms gov pressure sensor with wires for it. .

The GM solenoid and new governor housing is $140 from Suncoast or PATC, the OE transducer is $50 online. Not sure what they are selling you for a combined $340 unless its markup.



You could just go with the OE transducer and the new Borg solenoid at around $100 combines and see how it works.

 

[Hammer]

I'd second the call to Goerand or call NADP myself.



Either shop can build you the trans to hold or do what you want.

 

[cerberusiam]

Either shop can build you the trans to hold or do what you want.

No doubt they can. Neither can ship it to Finland for less than half the cost of the trans though.



He posted shipping is $1200 each way. That kinda takes all fun out of it when your on a budget.

 

[subodh]

- Sonnax inputshaft

- Sonnax accu pist. kit

- Sonnax 2nd gear servo

- Sonnax rear piston

- Sonnax raer piston plug

- Sonnax 2nd band strut

- Transtar press sensor

- Transtar guvenour sol.

- Red alto Masterkit

- Transgo shift kit

- 2nd gear band lever

- 3disc converter.



please tell me wath you think about theese parts.

this is from my local shop and the parts are abit cheaper chan dtt

also its taxes and shipping included so its alot cheaper in fact

is it worth a try or isnt sonax transtar somthing to go with?

PLEASE TELL ME I NEED TO GET PARTS SOON IM STUCK WITH DRIVING A NISSAN

 

[cerberusiam]

If the price is right, those are decent parts. Thats pretty much the basis of a solid build.



You need to add a rigid front band. Don't even try to run the flex band with power upgrades.



Clutch counts in the forward and direct, if you are going to play hard those need to be increased or you will just eventually smoke the clutch packs. Check with the local guys about how to increase the count of standard size clutches and what maching needs done. A lot of solutions use thinner clutches to increase the count but they don't handle heat well and can give issues in a short time.

 

[subodh]

so this will do

yes its more clutches and a better band, didnt go for kevlar. The guys here doesnt have much dsl experienc but the guy who is selling me this told me that we are building a transmission thats stronger than that he has in his dragrace car. The shop is only building american cars and have a good reputation (their race car is a gas v8 and makes under 10sec an have once done a low 9)

 

[cerberusiam]

Sounds like you and they are on the right track, but, you have to remind them this is NOT a 2000 lb race car with considerably low TQ and a high stall converter. They MUST take this into account or you will just smoke their race car builds easily.



Be sure to tell them you will be putting 1000 ft\lbs of TQ thru the trans at 1600-1800 roms, per your build specs. That puts a different spin on things. The front band (2nd gear) must hold that with the TC locked, as will the diretc clutches need to hold it. The only way to do it is good material, more surface area and more pressure at low rpms. On the way they MUST address the forward clutch pack. This gets forgotten too often in a diesel and you will end up welding the clutch pack on a boosted launch or low rpm full power runs.



As many clutches as possible with as much pressure as possible then you have a problem with the OE clutch pistons warping and sealing. Billet pistons in the direct and forward clutch packs are almost mandatory if you are gonna twist it hard.



Make sure the TC builders understand how a diesel makes power and where or you will end up with a sub standard product. You want as low stall as possible with as much efficiency as possible to make it work correctly. The must do some custom stator work or you loose too much at high throttle and transition form fluid coupling to lockup on a triple is VIOLENT and will break things.



The truth is if you don't spend at least $1000 on the TC alone you will have a weak link and transmission killer at a critical juncture point. Gasser TC's are only going to work in race type vehicles that weight much less. You have a 7k box car to accelerate and that takes a different approach front front to back on the trans.



You will have to address OD clutch pack also under high power. Once you have the trans putting the power down you will want to get into OD on a timely basis to load the engine and make the speed\ET. The stock OD setup won't hold, it needs more clutches than look at the OD pinion and you will want to exventually spring for thta $400 steel cage steel gear planetary gear or BOOM at an inopportune time.



I am envious, sound slike a fun project. Wishing you best of luck.
