I was wondering if i was to upgrade my trans...would the FLT level 4 4L60E bolt rightup and if not...what would i need?

 

yep, fits right in there, the level 3 and 5 will also as long as you are replacing a 4L60e or 4L65e

 

what Tranny if i plan to do one....I see that a lot of guys swear by FLT....if so..what level if i plan on doing mods and mayb a supercharger in the future?

 

level 5 is good to around 500. They definantly have an excellent reputation, but you certainly do have to pay for it. They seem to be at least 10% more than anywhere else.

EDIT-Don't get me wrong, I'm not ******* on them. I have yet to hear of an unhappy customer of theirs, but price is certainly an issue for me personally

 

I have the Level 5. I am probably close to tolerance with it but it behaves flawlessly.

 

Anyone hear of level 10 trans in NJ...hear they do good work! neone familiar?

 

same here!!!

 

if you took out a 60/65E one of their's will bolt right in with no problems or modifications needed... only if you have one of their vac modulated units. then, just run the vac hose up to the brake booster hose, cut, put in the T, and your good to go.

 

Youll like the FLT....I promise. Itll bolt right up and take asswhipping after smokey asswhipping.

 

Just thought i'd point this out. He has a Yukon Denali, so his brakes are hydroboost rather than vacuum. Just a small detail
