4l60e pump swap old vs new??
Is it possible to use the input shaft and drum and pump from my 94 and use it on my 98 trans so I can use the stall converter?
I think it "physically" should work and fit.
However, the '98 has a PWM TCC valve and the '94 parts will not be setup for that. The solution is to disable the PWM TCC in the valve body with a different TCC valve and (perhaps) with either a '94 separator plate or mods to your '98 separator plate. I don't know the details, but I see references to them and believe both Sonnax and Trangso make the "retrofit" non-PWM TCC valve.
Hopefully a more experienced person can confirm and/or correct this.
