Just install 4th piston yesterday!!!!! Took me long time to put cover Back.=)
damn thing wasn't going in easy!!
Big difference I notice from 3-4 gear, Holy ****! I wasn't expecting that much difference, servo does hold much much more from 3rd to 4th!
Yeah! gas mileage lost little bit, but who cares!!!(all about shocking rice boys with imports!!!)

 

Jeez, I never even get into 4th gear anymore Cograds on the upgrade!

 

thx! I had to go over 80 to get in to 4th. damn!
i'm getting stall converter next. thinking 2600 to 3000. Any recommendation??
i feel power in my Denali(specailly after Heads and ls6 Cam, but cant delivery it right on time due to auto tranny.
i using it DD so can't get so rough on Stall.


Getting serious boost soon!!! Custom FMIC with Whipple Charger!

 

I would recommend Yank or PI for a converter, depending on your needs and budget.
Do you have tuning? If not you really should look into getting a good tune for your mods. Transmission shift perameters are adjustable in the tune.

 

I got tune from Westers three times, shift parameter has been tuned too.(thx to Westers' Awesome tuning) but i think I need it again because from 3rd to 4th. there not enough gap between them, it's like 100 rpm
I thinks it's stall ready tune now. all i need is stall to match it. =)
