4080E Solenoid kit
2 days in on the replacement kit for the 4 solenoids and pressure plate and wiring harness. It fixed my shift delay and thunk into first gear at stop lights, it shifts smooth and so far no over pressure hard shifting which was intermittent. Parts are good Quality AC Delco or similar Quality (didn't see a manufacture on PS manifold) and fit great, even the harness snapped in good and tight and wire lengths are correct. Worth the money and was a fairly easy job to do myself.
