Drivetrain purchase help

Happy Thanksgiving!

Will be making major purchase and wanted to get some feedback and thoughts on a few different options I'm considering. Down the road I plan on installing a blower. Questioning wether 4l70 transmission would be up to the task. Please post any pros & cons, all feedback appreciated.

Option 1 being the LS3 480 with 4l70-e trans connect and cruise (gmpp controllers for engine & trans) $12,700 with what appears to be $800 rebate thru 11-30 so $11,800

Option 2 being same as option 1 but upgrading to 4l75-e trans (supposed to support 650 lb-ft torque) not sure on cost & if rebate would still apply)

Option 3 being LS# 480 with 4l80-e, PSI conversions harness with gm controllers for engine & trans. Basically $12,000

What I'm thinking is that option 1 would be easiest install but possibly weak link in trans when install a supercharger?
With option 2. Is the 4l75-e really worth added cost, have weak areas of trans really been addressed?
with option 3. How difficult is installation of 4l80-e in 67 firebird? Am I giving up any features (really like to run 2 tunes in trans) by going stock vs gmpp controllers?
Can you think of an option 4 I might want to consider?

Thanks for your time. Hope your day is filled with family, good friends and good times

Re: Drivetrain purchase help

When deciding on a DT you have to determine the weak link. I always design/build so my weak link is the tires. Unless your all our racing with slicks the tires will spin before anything breaks.

If planning on a supercharger down the road I would not start with an LS3/480. I'd probably look at a 430 with a plan to run a blower cam when I install the SC.

Why do you want 2 tunes for the tranny? Set up correctly with the right TC should do whatever job you want it to do.

Good points. Thank you. Thought about the 430. Isn't the only difference between the 2 a cam? Figured I might as well have 50 extra horsepower for the 2-3 years before the blower. Then who knows may only need some sticky tires and never even install a blower. If I do, figured easier to sell a more aggressive cam than the 430 one?

Like the idea of having a street tune with firm shifts and then race tune with neck snappers for those full throttle blasts. Maybe more trouble than its worth. What do you recommend for TC? The GMPP ones or?

IMO go with the 525 HP and you'll never want the blower.

With the GM ECM you can adjust Torque Management. Ie shift points and firmness up and down using HP Tuners then reflash when you want to between the two. I believe there is an aftermarket flip tune module as well available but not sure.


That said it's sort of old school shift kit logic that really doesn't apply now days with ECM engine and transmission management. Plus if you go with the GM Performance engine and tranny you keep your warranty by not fooling with it.

Run the TC that comes with the package
