4L60E Question

[cade75]

If running a 5.3 or 6.0 swap to a 98 V6 Camaro will a ls bell housing and different input shaft be all that needs to be change or will I have to swap the tranny out all together?

If I'm not mistaking the ls1 4l60e should bolt right up to either one of those motors.

I kind of miss phrased the question, on one of my other threads they let me know that the bell housing on the V6 is a different angel and will cause clearence issues and the input shaft was different as well. I didnt know if I could these and still use the tranny off of the V6 or should I find a used unit off of a V8

There's no difference in the 4l60e between the 3800 and the ls1 other than the 3800 uses a 60 degree v6 bell housing.

Input shafts are the same.

The 60 degrees refers to a style of block (60* V angle) not bell housing angle.

The 3800-II and III is a 90 degree block that uses the same bell pattern as the 60* v6.

Change bell housings and your in buisness..

To add:

The 3.8L should also not be confused with the 3800.. They're 2 different engines.

The 3.8 is a BOP engine with a BOP (Buick) bell patteren, and a substantially different engine than the 3800-I-II-III.

The 3800 did retain a few characteristics from the BOP 3.8L v6 though, one that is noted is both use some specifications that small block v8's use.

These v8 characteristics can be traced all the way back to Buick Wildcat days of the 1950's.

The 3800 has a lower deck design, and utalizes a balance shaft, amoung other changes...

With the lower deck and other block changes that were made for the 3800 the BOP bell pattern was dropped in favor of the 60* v6 style.

Changing over to the 60 degree bell pattern afforded the 3800 to be used in a larger variety of applications including the then "new" 4th gen f-body.

Smittros advice is right on the money except for the fact that the 4l60e's are infact different. The v6 uses a smaller splined input shaft, torque converter, servo and different valve body routing. This isnt fro just me performabuilt has posted several times that this is the case you will need a v8 4l60e preferably from 98-up to do the swap. also one other thing to be noted of is that a truck 4l60e will work but the tailhousing will be different. you will need a fbody tailhousing and put it on the truck tranny or get one from a v8 fbody

You are right I looked it up just be sure and it is in fact different.

Yes this is correct, the bell housing, the input shaft is smaller, and they use a 554 servo which is never a good idea to use since it has such a small apply area, in fact when I rebuild them I use the 553 servo that orginally come in the trucks, if you get a truck trans make sure it is from a LS style motor 5.3, 4.8 or 6.0
