hello guys. im new to the forum. i wanted to join a gp forum because i have a bone stock gp gt other then my performance chip. i wanna put 5 or 6 speed transmission in my gt but i'd like it to be an auto(sissy i know) i want auto because i have a problem with breaking my right hand so it gets hard to shift,lol. just wondering if its possible and how much it would cost. and what i would have to do. thanks guys
 


Welcome. Please tell us more about this "performance chip". Six-speed swaps have been done before, both auto and manual, but it wouldn't be worth it until you got some powah!
 
What benefit are you trying to achieve by going to a 5 or 6 speed automatic?

And I would love to hear more about this performance chip as well
 
The GF performance chip reprograms your air/fuel ratio,ignition timing and other aspects to safely increase the power, while increaing fuel economy the chip is designed to make your car run smoother and cooler at the same time. check out website.gfchips.com and as for the tranny i want a 5 or 6 speed because i was looking into dropping a v8 into it. like i said i am a noob to the whole modding a car so whatever you guys could help out with without looking down on me too much would be great
 
or swapping for a gtp motor and modding from there. im not quite sure what i wanna do. so i'd also like opinions from real gp fans. im just coming into my own on the car and have seen fantastic things from them
 


Most GM automatic gearboxes are going to be 4 speeds. You only need 3 gears to get down a 1/4 mile.

As a matter of fact, off hand, I can't think of a GM with an automatic gearbox that has a 5 speed. Most cars with 6 speeds are cruisers anyway.

As far as dropping in an LSx, there will be A LOT of custom fabrication involved. I think the last person to RWD swap a GP spent 20k. There really isn't a reason it can't be done, but the time and cost involved would be more than the car is worth, especailly when you can get a good turbo setup and run 10s and 11s all day long for a fraction of the cost.
 


just get a whole ls4 cradel and bolt it up you pansie, motors can be had for 2500$ dont go into craziness. i think you need to stop thinking your shadetree mechanic lol
 
So lets sum this up.

"Performance Chip", dangerous garbage.
V8 swap, not worth it.
Six-speed swap, you do not have enough invested in your car yet.
 
Chips are junk, a pcm from a vendor or tuning software are the way to go.
V8 swap, probably not worth it. If you wanted to go V8 I suppose a GXP swap wouldn't be the worst thing to do, but that's an LS4, and front wheel drive.
You can do a getrag manual swap. Do a search for Kuntzie, his install went smooth.
