4L60-E Transmission Pump RE-Assembly - Transmission Repair
This is a late model 4L60-E pump. If you notice that the TCC apply valve and the pressure regulator valve spring and boost valve position has changed. It was to accommodate the input speed sensor we see in the later units.
The early model had double springs on the slide and also on the TCC apply valve. Castings were changed but the assembly stayed the same.
Bushings need to be replaced as always, alignment is done with the same tool, with the exception that it doesn't take a pump O ring.
