Tranny has had a stroke!

[grayhoe00]

Yep tranny has had a stroke and not sure if she will make it....SO...
i need help. I am looking to do a 6.0 with a charger. What options do i have for a tranny, like rebuild the one i have, buy another one, ect. I want it build so i do not have to worry about it no matter how much i hammer on it. Keep in mind it is a DD...

If you're gonna do a 6.0 just try and find one with the tranny attached. The 4L80E should be able to handle it, and you could always build it up before the swap.

Performabuilt or Finishline Transmission, check em out.

which one is better?


after taking it out at lunch i have figured out its the rear end.....and from what the guy at a local shop said there is some slack and its causeing the tranny to get confused....

 

[blueflamed03]

Ive heard good from both, I'd just check and see which one best suits your needs and price.

 

[grayhoe00]

The 80 will require a lot more work.. Modified frame support, and different wire harness. NOT a direct bolt into a tahoe

so what tanny did you go with, and why a lq9 and not a lq4

LQ9 is the ** version, My thought was if im going to do it... Do it right lol -
Better components to them. And I found it with less miles than an Lq4

I currently still am running my stock tranny - no issues at all, and am going on about 50k miles ...and I'm not easy on it.

Once it goes I'll do 4L65 - or something built a little stronger.

LQ9, higher compression
LQ4, lower compression, good for blower.


You can have a 4L60e built into a 65e, and a 60e built tough, like a Level 3 or 4.
