Whats goin on guys? Ive been a member here for a while but never really had much to post..

i just swapped a LQ4 into my 2000 NBS tahoe..also did a Transgo hd2 shift kit and a vette servo..trans is a 4l60e that was flawless before the swap

the motor runs great, such a step up from the 5.3..but i can hardly drive it because i dont have 2nd gear..

i have first, then it holds until about 2200 and then if i let of it shifts into third..i have 4th and lock up as well..if im just normal driving it drives fine, gets up to speed quickly merging and passing, no issues..

if i drop it into 2nd manually, it just spins..

what do you think it could be?

from what ive heard i could of messed up the servo..

i bought a vette servo, and then installed it the way trans go says..using a shim under the cover, and flipping a few things around..

everything was done by the book

should i take that servo out and just install it normally, with no spacers and no moving/adding parts like trans go says?

what else could it be? im new to trannys, but we followed the instructions to a T and double checked everything..

Sorry for the long post..thanks guys

 

any help? im going to start by pullin the servo and redoing it just to make sure its good to go..then from there i guess ill pull the valve body again

 

Assuming your valve body install was flawless, the easier job would be to check the servo. Those are pretty straight-forward when it comes to install. Only catch is, check the seal around the 2nd apply piston. You may have leak-by. That's the first thing that comes to mind with regards to you having 4th gear, but not 2nd.

 

took it apart tonight..damn 2nd apply didnt have a teflon ring..i musta spaced it when i put it in..i was 40 hours into the motor swap in 2 days so i was goin a little crazy..

got that put in and all WAS well..had all gears..then the damn snap ring didnt seat right so the cover popped off and i lost all the fluid down the road..just got it put back together so well see how it is once i get some fluid in there

 

Hows the 6.0 do in the tahoe? I always wanted to put a 6 litre in a tahoe. Any track times yet?

 

hope you didnt crack the case....

 

huge improvement over the 5.3..better mpg as well..no track times though..i need to get some stock tires on there as the 24s are heavy as hell..


ya im lucky i didnt crack the case, but all is well
