Yes.
4L60E also know as a electronically controlled 700R4
It came factory with a 4L60E transmission.
That would be the 4L60E trans.
4L60E OR MAYBE A 700R4
my truck has a 700r transmission in my 4+4
700R4
The S10 was available with the NV3500 manual or the 4L60E automatic... those are compatible with the Silverado 1500 trucks (except for the 454SS).
a 700r4 trans out of a s10 with a 4.3 will bolt up to a 305 but you will have to use flywheel cover for the s10 trans.
That would be the 4L60E transmission.
4L60E automatic.
You can put it in there BUT NOTHING will work right and the engine won't even run right. You MUST put the 4L60E transmission back in it due to the COMPUTOR system in the truck.
That would be the 4L60E transmission.
