Have a 99 Trans Am / Auto w I believe the 4L60E it has a 3600 Stal and im wondering if theres anything i can do to tighten the stal up.. Heard there was with some special fluid or something.. Anyone kno about this..??? Thanks

 

What gears do you have? If you have 2.73s or even 3.23s it'll feel alittle loose. ( my 99 came with gu2=2.73s) A set of 3.73s will tighten it up alot. It's really the only way...When installed, either increase line pressure with a tune, or install a shift kit.

 

I believe the rear end is completely stock, which Im not to thrilled about but I will get there eventually.. So whats that the 273s..???

 

2.73s are the shittiest gear ratio you can have. GMs pitch for a gas friendly ls1..I ditched mine as soon as I bought the car for 3.73s. Made a huge difference..Really woke the car up.. It "feels" like you pick up 40hp, throws your head back in your seat. Essentially your tires spin faster.

 

Agree, except I ditched mine for 3.42's and have been very happy with them. I hated and planned to get rid of the 2.73's the day I bought the car - even with the stock converter. Some guys are fine with it, but I can't imagine driving around with a 3600 stall and 2.73's.

 

Tell me about it I def dont like it.. lol Guess I have a few options ill be looking into.. Thank you both
