Can anyone make a 4L60E live?

LTOne4Fun · 06-29-2002, 09:40 PM

I work at a Fbody Prformance parts and install shop, and wwe've been trying to figure this one out. We dont build the trannies ourselves, but we're trying to come up with some idea to make them live. We tried finding a stronger forward drum, but it seems none exists. ANy knowns remedies for having snap rings break? Is that a result of too much line pressure or?...

We have a 10.90 LS1 heads and cam car here that just blew apart a tranny that was built by one of the bigger names in 4th gen Fbodyland, and it was supposed to be able ot withstand 9 second passes. Who makes them live? We just converted a 6 speed 422 C5 to an auto in hopes of less parts breakage (tranny output shafts and Dana rears), hopefully the Rossler tranny holds up to it well

Check out the motor trend that has the lingenfelter corvette vs. the fighter jet. The vette runs 9.20's @150 with a 4L60E. I can't remember the name of the company that modified the trans but I think it was Rossler or something like that.

part are basic nothing Crazy.

Off the top of my head I used a Superior VB kit, .490 Boost,4340 Sun Shell, Sonnax 3rd gear Accu Check valve, Factory frictions and steel's, 4L65E planets, and a Yank 3,800 T.C.

You want to know the REAL key? Programming

They will NOT live forever no matter how much you build them I will not lie to you. Then again neither will any thing else

I used to go through up to FOUR TH400s a season. I could rip the input shaft out of them almost at will. This was with a 327

I killed some of the best transmissions made before I started building my own

Feel free to E-mail me. I would like to hear exactly what you are breaking.

Well, Ellis thanks for another great build on my car. The Alto red Band and 3/4 clutches do hit a lot harder on the street. After playing a few days I have already got use to the shifts (3200 PI helps). Now if I can just find the false knock with the long tubes!

Oh, and here is Ryan's 11.00 car Ellis, with now a 10.97 @ 125.3 off the gas at the end (bracket racing), 3700lb race weight, with alot a rwhp....You build some "Kick Ass" tranny's

Try a C-6 rear planetary snap ring to go in the rear ring gear.
