New trannie and lost power

TURBO32VALVE5.4 · 12-11-2008, 12:47 PM

I am stumped with my new trannie set up. I was at 710 RWHP @7000 RPM threw my 4R100. That lasted 1 weekend and nuked that trannie, I stuck in a lentech 4R70W and now im at 670RWHP same rpm and mph on the dyno. What gives????

why did you switch trannies???? and are you still using a lockup converter and locking it on the dyno just as you were with your 4r100???

It's a non-lock up, I melted my 4R100, I here they dont like high RPM and my truck comes alive arround 5K

if the 4r100 combo was a lockup then that is your problem.

power loss.....a locked converter will transmit more power to the wheels.....

Paul pegged that one!!

What/who's transmission did you run (4R100)?

typhoon43 · 12-11-2008, 04:52 PM

Any reason you didn't go with a lockup converter? Less heat when cruising, more power applied at lock up. Not sure what the advantage of a non-lockup unit would be. I'm sacred to see your 4r100 ate it due to the 4V loving the higher revs. Mines is almost finished... It seems now I need to start preparing for a tranny swap.

Well I got the lentech 4r70w and the converter from a friend who was not using it. I can def. tell you that it rev's twice as fast and there is really not that much lag at all. It will spin my 555R's at 60mph, I just like to see the big HP#s on the dyno but the truck feels faster with the lentech

Jamie V · 12-11-2008, 05:11 PM

On there website they list a converter for all the 4r70W as lockup converters????

Street Terminator PLUS AODE/4R70W

BTS told me I will not have any issues with his tranny spinning it close to 8K......PSI has another turbo truck with a BTS and spins that one close to 7K without any issues. Not cheerleading just saying what has worked for us.

i agree and i dont think there was any need for the changeover...they can handle it when built properly.....

TURBO32VALVE5.4 · 12-11-2008, 06:55 PM

well if thats the case I am going back to the 4r100 I really dont like the lentech.

Paul, any difference between my C6 and the 4R100 that would cause one to handle more/less rpm then the other?
