just got my Level 2 Performabuilt 4l60e installed, so far im very happy (only took a drive about 15 miles)... i hope this time it will hold longer... shift from 1 to second is firm but was harder with my stock 4l60e, transgo shift kit and corvette servo... u think thats normal?

 

my 1-2 shift was hard too, i tuned it a little softer, but frank told me if i still don't like it i could swap in the vette servo instead of the billet super servo for a little less harshness, and have no ill effects on reliability or power capability.

 

i send my computer to texas speed so they set my line pressure to stock... even its not very hard now, i guees its still durable right?

 

your gears shouldnt SLAM. a quick firm shift is all you want. slamming gears is where you start breaking hard parts.

 

plus one on that bud ,u want a quick soft shift .every time i had a tire chirping shift i broke an input/output or more .use it like it is or youlle break something.hard shift in heavy truck doesnt go good.especially if u have traction ,o youlle even be lucky eniugh too break a rearend also with a hard shift and good traction.as long as its firm and quick ide leave it.good luck

 

I am thinking of buying the performabuilt Level 3 for my turbo 5.3 how is the trans do you recommend?

 

Think thats what happened to to my level 2 it would chirp the tire on every one two shift over half throttle and one day it went pop and has no gears to it.

 

i recommend

 

yeah your line pressure needs to be dropped if your chirping 1/2 throttle

 

So is he good especially the lvl3 trans?
