4L80E In A CTS-V...Fits Better Than You'd Think
#21
TECH Fanatic
The whole reason I got the V was because it is a stick and the wifey can't drive it. Though if you are going to run drags, I don't think anyone can argue that an Auto is way better

Yeah I'm stuck on this issue too, it will be extremely difficult to get passed mid 10's with the manual, but I'm told that the autos will make my car **** from roll races...
I want to go tear **** up at TX2k next year, so not sure what I wanna do...
I had my eye on the TCI Sixshooter with paddle shifters: http://www.tciauto.com/tc/6x-six-spe...e-shifter.html
But dont wanna lose my roll power or ability for road track....

4l80e
I got my V running with the manual but just too much damn wheelhoop and I am still getting vibs....We bled the Mcleod rxt twin...Got all my gears now and reverse...but NOW at 3/4 throttle 4th gear pops out...I was going to sell thr V, but I can't till I get that fixed...A 4L80E even stock would help..I have the 06 with 58x reluctor....What all electronically would I need to put the automatic in. I was going to have a local give me a price but never talked to him for I think with his Ford 4 link and auto with cage, carpet, and a show piece type shifter is gonna cost me a bundle...Just might take off the tags cause of insurance prices and put it on my lift and get some help for my new project.
Thanks DMM for doing what I never got around to doing...great job. Nice pics..

Greg - If your trans is popping out of 4th gear under load you have internal trans problems...most likely excessive bearing clearance from the description you provided being that 4th gear is the input shaft on the T56. All the torque you have probably beat the hell out of the input shaft bearing causing excessive clearance. It could also be the actual gear itself, the shift fork pads, or the synchronizer keys. Whatever the culprit is, it lies within your trans.
The 4L80E can be controlled by your existing PCM, however it may require a segment swap. I am still trying to find out if the 4L80 can be controlled by the PCM on the 04-05's with the LS6 and older PCM, although I'm pretty sure they can be. The 4L80E harness would have to be pinned to the existing PCM harness which is time consuming but pretty easy.
I know you've been going trough hell with this thing, if you still have my number give me a shout.

As long as you retain the OE PCM, there is nothing to be done. The stand alone controller would be the easy route, although you may be able to do the segment swap and re-pin the harness to control the 4L80E. The stand alone controller would not be integrated with anything else, so the PCM would assume the T-56 is still in place.

Yes, it does. All you have to do is splice the signal wires so the PCM gets the reference. You also have to go into the tune and change the VSS pulses per mile and trans revolutions etc...but that's easy to do with any tuning software and you just have to pull the data from a 2wd truck/van.
If you need a file to pull the VSS data from, PM me...I have a 2001 2wd Silverado file with the appropriate data.

Just looking into this for the wife. I have a 4l80e in my LS mustang as well. But she asked how hard it would be to slap an auto in her V. I decided to look into it. So in theory with the stand alone, you would just plug up the stand alone, bypass the clutch switch and tap into the VSS?

Bump to the top! Found a guy by the name of Yanick Dumont that did a successful job of putting an auto (700r4) into his V! Come check out the thread on my group (pinned to the top)... BTW, anyone speak French? He’s in Quebec and doesn’t speak English! I've been talking to his friend who speaks some English who is going to try and translate the build and give it to me!

A 700R4 (4L60) may live behind a stock V1, however a modded V will make short work of it. With the weight and performance potential of our cars the 60, 65, 70, 75 series transmissions simply do not have the strength to last for very long.
If you're going to go through the process to get an auto trans in there, you might as well use something that will last.

i heard the V2 guys pushing in excess of 1000HP have switched to the truck tranny 4l60. pretty sure the 1300+ HP twin turbo V's are both running this same trans. no paddle shifters though
