Shops in Western, MA or CT for 4L60E build/install? RC 3.5" lift i

brian9095 · March 15, 2014

I own a 2007 GMC Sierra Crew Cab NBS 4x4 with a 5.3L with 28K on it. I'm interested in building/swapping the transmission for a built version better suited to frequent hauling/towing considerable weight and up to 500 ft/lbs torque. Bulletproof comes to mind. If I could do a modded 4L80E "affordably" and it not be a hack job, I'm game. Whenever my budget recovers from the transmission, I'll move to differentials and engine mods. I never race the truck or travel off-road beyond a boat ramp or to park near a trail. I plan to keep this truck for a very long time.

While mechanically inclined, I no longer have access to a lift (or a garage). I'm hoping someone might know of a reputable (and reasonable) shop to handle the transmission build/swap? I'm also looking to have a RC 3.5" suspension lift installed (both control arms, tie rods, u-joints). I'm in Western, MA (01085 zip) so I'm near Northern, CT and Hartford but willing to travel further for a talented group.

If anyone has recommendations for mods to build me a nice comfy bulletproof tow truck (short of suggesting I buy a 2500 or swap to a 6.0L e.t.c.) - I'd certainly love to hear from you. At this point, I'm fairly clueless with LS motors, GM transmissions e.t.c. Been busy racing Mazdas..

New ported/polished heads, matching cam, intake manifold, headers/exhaust and ECU tune should put the 5.3 in the 480ft/lbs torque range without FI. Is that reasonable?

Thank you in advance!

dynamic transmissions in Branford is really good and well known. Cant give you an exact quote but it will be between $6-800 for the rebuild and comes with a dyno test for whatever hp you choose and 6 month warranty.

Hitec I believe it was called in East Longmeadow Ma. was a good transmission shop back a few years ago when I had to rebuild my 4l60e for my old s10 zr2. No way though they will do it for 6-800 dollars, not sure if you know the guy personally bird but not a chance are you going to get a rebuild done on even a 4l60e trans for that low, I think in 1998 mind you I paid well over 2500 for the rebuild and that was one of the cheaper quotes I received. I imagine it's only more expensive these days!

I was talking just to rebuild no parts included. You can get a rebuild kit rated for 800hp for about $700 and then a single disc stall for $800. That puts you right in the $2500 range for a full build.
