Engine/Transmission (1994 - 1998) #5 plate installed.

[PullinRam]

Well last night i finally got around to installing my #5 kit from TST. I was waiting to get my 4. 10's/detroit done before i put the plate in. Talk about night and and day difference. If i lay on the throttle hard she wants to break loose and slide sideways. But i didn't put my plate in for street performance. I wanted some serious pulling power for the woods. I am the main truck that alot of people rely on to get them out when we 4wheel.



I am also on the local SP barracks pull list. They call me if they need a pull or some poor innocent person is stuck and the troopers can't get em out.



Thumbs up to TST. Great product!

Well everything is great so far with the plate. But i can feel the the TC sort of vibrate/slip i think when i step on it hard in OD. Does this mean the TC is goin south on me already or i just need to back off on the throttle when in OD? Otherwise the truck pulls like a freight train if i stay steady on it w/o bein hard on the throttle. And the plate gave me some serious power off-road. I used it a few times last night pulling some stuck friends out.

Anyone know?

Your t/c is probably slipping, mine is a 5-speed, it took a couple miles with the 5 to slip my clutch. Sure does seem like a different truck doesn't it! Power is bliss!

Upgraded Trans

Pullin Ram Your signature states an upgraded trans, does it still have the stock torque converter??? What are the line pressures?? WOT line pressures in OD??



The OD clutches rarely slip, unless there are other issues in the trans. Usually it is the TC lockup clutch in a stock TC.



The best advice is to keep the RPM up above ~2000 in OD so there is as much pressure as possible available to keep the TC locked when you get into the pedal.



Use your OD button to control the upshift to OD. Don't expect the TC to hold all the new torque from the #5 plate when putting around at 1500 rpm in OD.



Otherwise a better trans is in order.



Hope this helps, Greg L The Noise Nazi

I put a #3 I think in my 95 and the torque converter started slipping when I was pulling a heavy load. Ill say this your transmission,s days are numbered unless you really have some self control. Ha anyway I just bought a# 5 for my new to me truck also added a 16 cm housing looking forward to trying it out sounds like you were pretty happy with it.

LSfarm, I had my stock trans rebuilt/upgraded about 1hr ago. I had the guy put in stronger bands, add more clutches to the tail end, a trango shiftkit, and a beefier TC. I know it wasn't a stock TC he put in but one specifically built for towing apps. I figured that would hold better for the time being. Can i just order a better TC and throw it in and be set? Or do i need more upgrades?



Oh and i don't know the line pressures. Any way to find out?

Thanks

Line pressures

Well just about anything I say is going to sound like I'm throwing rocks at the the guy who worked on your trans. But to be blunt, there are several trans companies that make components for our Diesel transmissions that have proven the test of time and added horsepower.

It sounds like the TC you have or the rest of the trans that supports good line pressures is not up to the task. Sorry.



The line pressure can be tested with a 160psi gauge, 6ft. of hose and a 1/8th" pipe adapter and put it in the second fitting in the passenger side of the trans aft of the bellhousing. Your trans guy should have this gauge setup.



There is an awful lot that goes into a trans that is capable of holding and living with the torque from a turned-up Cummins engine. I really can't advise just adding a different TC without knowing a lot more about the trans as it is now setup.



My best advice is to try what I suggested above, using higher rpm to assist the TC clutch to hold the torque from the #5 plate. See if this works. A lot of stock transmissions have held up to a lot of HP just by careful use of the available power. But to be honest a lot of these transmissions could be slipped at will with a heavy right foot. It doesn't take too many applications of heavy pedal to trash the trans and leave you with a stranded truck.



A slipped clutch=burnt linings which contaminates the ATF with lining material which circulates through the trans and causes other problems which compound each other and cause the total failure of the trans. Drive it carefully so as to prolong it's life as long as possible.
