What's the difference between a LT1 and v6 4L60E?
What's the difference between a LT1 and v6 4L60E? Just trying to gather some info on what the differences in our transmissions are. For instance I know a lot of us have ran a 96 4L60E in our 94-95 cars with no issue, and from what I have been told the 97 is different. What about the v6 transmissions? So say would my 95 trans bolt up to a 3.8L car? Or is there wiring to be done to make it work?

I mainly ask since someone is interested in my spare trans that I'm selling and it would either be going in a 96 truck with a vortec or a 98 3.8l camaro. Just don't want to sell it thinking it will work and won't.

From what this says that's all the gms that had the 4l60e I think some of the 97s had the 4l65e which I think is a bit smaller but I'm almost positive both have a removable bellhouse so the general could slap em into just about anything

Neither of the 3 trans that I have, have a removable housing. 2 95's and 1 96, the 96 is in my car now, and I have 2 different 95's laying around. I would assume the bolt pattern is a standard sbc bellhousing but that's why I asked I'm curious.

It depends upon which V-6 you're dealing with...
The 3.8 is, as mentioned, is a 60 degree V-6 and is not interchangeable with the V-8's. But, a 4.3 is a 90 degree V-6 and uses the same bell housing bolt pattern as the V-8's.
The LT1 cases also had the outer "ears" cut off of the bell housing for exhaust clearance. The early S-10's used this style as well. In '96 the S-10's went to the removable bell housing configuration.
The '95 electronics are unique to the 1995 model year.

Interesting as I have a 96 trans in my 95 car with no issues, what we're the electronics differences? I've been told the Tq converter lockup solonoid or something of the sort was one difference.
There is an additional solenoid that controls the rate of pulse/lockup apply. The engine harness for auto cars changed by 1 wire from 94 to 95, not counting the removable pigtail to the opti. Pin D6 on the blue connector at the PCM goes to Pin U on the trans case connector. the transmission didn't change electronically in 96 or 97. I don't think there were any mechanical changes from 95 to 97 either.

Yes, there is a difference between a 95 and a 97. I'm actually doing a write up on the an Impala forum on this for a 24x swap. but I'm learning a lot. It helps that I work in a parts dept of a dealership. So I have all the schematics and part #'s to compare.
So in any case, to the OP, One thing I happen to notice is that there are quite a few differences with the internals. Especially the solenoids. But I didn't go much further because the 6 cyl. doesn't pertain to what I'm doing.
So as far as the differences in years. 93-94 F-bodies do not use a PWM solenoid. It also uses a different 3-2 shift solenoid. In 95, the F cars use the same part # for 3-2 & PWM. In 96-02 it uses the same PWM as 95 but the 3-2 changes as does the harnesses between years.
The 93-4 uses one type of harness that does not apply for a PWM. In 95 it uses a harness that utilizes a connector that doesn't fit the newer 96-02 noid.
So based on all the solenoids, all the PCM is looking for is a specific resistance value (in ohms).
I verified a lot of this info with our trans guy at work and he's one of the best Trans techs in GM. He's just too old and ornry to carry on a conversation with. As soon as I get a chance, I'm gonna break into the old big books again to write down all the resistance values of each noid, which will help understanding it easier.
Here's a reply I got from Frank at Performabuilt, which I have their Lvl2 now. My harness is one that he refers to. it's made to accept OBDI & II. It has both type of connectors spliced in.
Also, here's a link to the thread I'm currently working on.

With our units though we didnt actually make any till O6 because of mods done to the PWM regulator valve it makes no difference which harness or solenoids you use so long as the match the pcm model being used.
For instance while you would never remove the PWM solenoid in a 94 it would only matter that the 3-2 solenoid was for 93-94-95 96 the 3-2 solenoid impedance changed so of course did the harness conector to the solenoid, After 96 all the same till 2008 when the input speed sensor ISS was added.
If you get the harness from FITZALL it has all the various plugs on the same harness and works with any solenoid type but again the 3-2 solenoid must be either 93-94-95 if for that year PCM and 96 up would be same from that point up.
Hope this helps
As for material around magnet not really unusual we actually now ask that people change the filter the first time at 1000 miles.
Thanks Frank
