I was told the 1750 was a oil pressure problem but I may have not heard correctly so who ever has the correct answer please answer.
The difference between street and drag racing,dyno is ? THROTTLE ANGLE unless I am wrong and that could be wrong, at this point I can live with i
Sir I am sure you mean well, but every one does not run large injectors and big boxes or large turbos.
The simple reason is if I am driving along and the speed limit drops from 70 to 65 and I have a trailer in tow the rpm have dropped to ( 3. 54 gears and your are 4. 10) where I have to drop to 3 gear lockup . The biggest issue for me is egts. I have a Gage so I watch them. If they are a problem then I will down shift not because of a transmission. You may not under stand now but that is the reason.
If your transmission is so much better will your vendor give you a 100 k warranty and no time line line. jimk
Jimk, Where did i say in my post I was running Mach 6 injectors or had an EGT or smoke problem? these are assumptions you made. In fact i specified I was talking about my Dad's tow truck,and I was very specific about the injectors,turbo and box i was running,when reffering to towing.
The 5th gr problem is partially the engine harmonics hammering away at the gears and shaft. The same thing happens with an automatic if it is lugged in lockup,that is the point i was making,
As for the oil pressure situation, all of my vendors transmissions Ive built havent had any issues,especially since my vendor uses improved seals,servos,accumulators and other details to acheive a very low amount of internal leakage. As for you being(told) it was an oil issue,again your an expert without ever having actually tested the leakage/pressures or internals of the transmission,I speak from actual experience,not what i was"told" about it. I have seen the oil flowing all over the bench from pressurizing a stock leaky trans that was very low miles,then modded it (parts/technology from my vendor)and seen those leaks diminish to less than 1/4 of what they were,those leaks can be measured with guages.
I was making a point that the all out holding power isnt even an issue at 1600RPM,at less throttle angle there is less torque,so less throttle valve pressure is required to hold the clutches.
Your sure I meant well?( Sir I am sure you mean well, but every one does not run large injectors and big boxes or large turbos. )
I bow my head oh great one... I have to think you are reffering to my truck here,so Im going to go with whats on my truck,and what i use it for. Again assumptions on your part, since my "big" box(which is the same one most others are using for towing/playing around) is turned off or on level 1 when towing with my truck. My daily driver injectors are 2. 5s, my twins are great for towing,and if you have ever read any of my posts you would know my truck is a work/tow truck first a race truck 2nd. I pull a landscape trailer a few times during the week,and almost every weekend my Sunnybrook 3310. All winter my truck is a commercial plow truck.
Whem i tow with my Dads 01 with 3. 54 around 65 mph,i end up at the same RPM,and dropping to drive is the best way to handle it,I have guages in both our trucks too,when im towing I use them as well,do you think this is over my head? what is it that I may not understand?

Where did i say my transmission was better?I havent downplayed anyones choice or investment. I was simply bringing up a valid issue that no one had talked about in this post yet. You come along make a bunch of assumptions and accusations. I always respect my fellow TDR members/friends. My posts and opinions are from experience,not what ive read,ive built a lot of these trucks,and have a lot to offer the members here. Posts like yours are exactly why those in the know in this industry seldom post here anymore. It also showed that we are not all on the same level here on the TDR, I was only trying to help bring to light what i feel is the real reason ( or a good portion) of the reason we shouldn't be below 1750RPM locked. As for warranty, my vendor has the reputation of being more than fair with his customers,even if they are totaly at fault for the failure, i have seen this first hand and know this to be true without question .
