Transmission oil pumps
I have a 1983 Chevy C-10 Custom truck it has a 700r4 in it but the oil pump is out and I have a oil pump from a 4L60 not sure what year the pumps look the same will it work if I swap it and put the oil pump in my 700r4?

Re: Transmission oil pumps
I got this on a search. I had heard this dat in the past.
In 1990, the 700R4 was redesignated as the 4L60 (4-speeds, Longitudinally positioned, 6000 lbs. GVW). This was a change in name only with no significant mechanical changes associated. In 1993, an important change did occur and that was the conversion of the hydraulic logic shifting system over to an electronic one.

Re: Transmission oil pumps
Figure out the year. Any stampings? The PWM pumps IIRC had a cast PWM .indication. While you can sometimes use a newer pump in an older unit, it may require oil passage, solenoid or other changes. And it depends on which pump you have.
