Differences in versions of 4L60E's
Up until 2003 the switch used two plugs, my 2004 harness used one plug. Both switches look pretty identical as far as bolting to my transmission so I don't think there will be a problem.
If anyone knows otherwise please chime in.


All this means it has to be at least a 1998 or newer F-Body LS style tranny. Now go get it, put it in the tranny shop and have it gone through and get on down the road!
I appreciate the clarification. The seller responded to me and this is what he said,
"nope i pulled this 4l60e out of a 2000 corvette that had a LS1 in it and the motor was in the front of the car and this it NOT a transaxle..."
Either this guy is a big liar and may also be lying about the condition of the trans, thinks he an get more money if he pretends it is from a Corvette, he's just an idiot, or he has vision problems and can't distinguish between a Corvette and a Camaro.
I've been searching the forums all day but couldn't find a definitive answer. There is a 4l60e 2wd out of a 2003 Savana van for sale 10 minutes away from me. I know it's recommended that the easiest swap with the 5.3's is a 4l60e from a 2wd truck from 2002+, does anyone know if the vans and trucks have the same transmissions? The guy that's selling it thinks they are the same. I called the local wrecker and he said they're different and that is what caused doubts in my mind.
Sorry to keep bothering you guys with these questions, i just don't want to make a mistake.

If the savana van is the GMC version of the astrovan the biggest engine in those were the 4.6 liter V6....which means the transmission may not handle the power with the 5.3.
Also make sure you get the park / neutral switch with the tranny because they cost around $30 new. They also changed the switch design in 2004 so if your engine harness is a 2004 + then you need that version of the switch which costs $55 + . Make sure you grab the dipstick too...that's another $30.
As hot rodders, customizers and racers we NEED to know why because there are tons of deals to be had on things that are close to what we need and can be made to fit with little effort. A perfect example is the 5.3 engine...
There is no wiring change to worry about. I am using a 1997 transmission and the only thing you need is an adapter from GMPP and the requisite bolts. The whole thing should be around $37 for the adapter and $28 for the 6 bolts. The biggest problem I had was the transmission fill tube, but I always use Lokar transmission tubes since they are only $80.

The tail housing on a new design (split case) trans has six bolts on the tail shaft while the 95 had 4 - no workie, workie.
Can a 4X4 be turned into a 2WD trans? Yes
Is it worth it? In my opinion - No
Unless you have all the right trans parts and tools laying about you will have to pay someone to do this. Factor in the initial cost of said parts and tools vs. paying someone who knows what they are looking at and it's cheaper to start with what you need.
second: so if im reading this correct a 99 truck 4l60e will bolt up and work perfect with my 03 lq4 in my trans am? the donor truck has a gen 1 vortec 350 in it...
I did this on my 5.3 swap but I am questioning my tranny because the guy that sold it to me may have lied.
I was going to try and find a used replacement and if I did I would look for something close to the same years as my 2004 engine for a direct fit. But that's going to cost a more $$$
But the guys at the camaro forum I frequent said to treat all used tranmissions as cores and inspect and/or rebuild. So I may take the one I have to a shop...and keep the adapter stuff too. It's a 1999 vortec tranny too.
Bottom line, depends on your budget and what you want to spend. Me personally if I had $1200 or more to spend I would get the period correct transmission. But my budget doesn't allow that so I'm making what i have work.
I have a 96 Impala ss im going to put a 05 lq4 in but my current transmission just lost 3/4 cutch. so to aviod buying a ltx trans when im going to go lsx soon I wanted to know if a lsx trans would work with my lt1 until i start my swap.
Thanks, hope this contributes to the thread
