Call FLT and talk to chuck. He will not try to over sale you, and will be honest on which unit would best fit your needs. A friend of mine has had their level 4 60E in his car that makes 525rwhp for 8 years without a lick of trouble.

I'm considering another FLT trans for my 07 Tahoe.

FLT is the way to go.
I was about ready to pull the trigger on a Level 4 (as that's all I needed per Chuck), but this Level 6 came available in the classifieds and was sent to Chuck for a refresh. He warrantied it like a new trans and it was just a couple hundred more than the new Level 4. Otherwise, that's what I'd have in my car right now. It's a good trans.

Trans Update Well I actually decided to go with the FLT level 6. However I added a couple uf upgrades. I added everything minus the 300MM input shaft. I also added the upgraded 1-2 gear set. Everything seems to be good so far Ive only put about 150 mikes on it as to date. And by the way the guys @ FLT are top notch as well.
