Well this weekend I'll be putting the new turbo set-up on my truck and I still can't decide what do about my transmission. My truck has a 5.3/4L60e in it and most people I've talked to said put a shift-kit and vette servos in it. I'll be running about 6psi with the front mount and intercooler, but I've got a feeling I'm going to want a boost controller to run about 10psi. Will the shift kit and servos be enough to handle 10psi or should I just go ahead and get a built trans??
Current Mods: 6.0/4L80e with Trick Performance Front Mount
Audio: Pioneer avic-d3, Memphis Belle, Two 12" Rockford Fosgate P3 shallow mounts, Memphis MS-Qs, and custom vinyl enclousure.
Yours trans will die with 10psi. Your rear end is also going to die if it is stock.
See this picture.

Yeah, that's what I was figuring. I'll probably go with a shift kit, servos, and a trans cooler for now... then upgrade to a built trans, converter, and better posi.

The shift kit and servo pistons are not to add strength as much as shift quality. Yes, the 2-4 servo mod can help save the 2-4 band but it's the hard parts inside (input housing, reverse input drum, planetaries, reaction sunshell, input sprag, output shaft) are what break under power.
Mine looks exactly like that! Wow. Mine took a dive with no where near that much power. It is still N/A. A built tranny is the way to go as soon as you can.Originally Posted by zeake

Well if that's the case I'm just going to wait and get a built trans... any recommendations? I've been looking at a level 5 from FLT but my buddy was telling me about Monster transmissions. Anyone have either one of these?

alot of guys on here use FLT. i hear good things. If I could go back I would have bought theres myself instead of getting mine built.

I would build a monster of my own in a heart beat but I would start with a stock trans for sure....not a "performance" build.
I can do it myself though.
My $0.02
I put the Century Transmission Stg III in my turbo Tahoe project
with a Circle D TB 3,000 stall converter.
4l60E / 4L65/70 Stg. III Transmission Build-Up :: Century Automotive & Transmission - Superb Products
Also running the Tru-Cool 40,000 gvw cooler.
This seemed to be the most cost effective upgrades I could
find for my build that should still hold up fine, but not break the
bank like a FLT Lv5 trans would.
I havent thrown any boost at it yet, but should be good to go
with those parts I think.
Next will be a Detriot Locker Tru-trac posi.

If you aint breaking - you aint going fast enough
If you're gonna wait and build a trans, then at least put a servo in.
