its been awhile, but aren t the fill/drain plugs on the right side? there are no drains on the cover plate, that I m aware of....are you talking about the vent cap?...got a picture?
Need some help identifying a part. There is a drain plug?under the left linkage pin on the 9 bolt side plate. I don't know what it is. Does anyone out there know? My transmission guy plugged it with sealer and now it is leaking.
that was GM s great idea to retard ign timing in high gear to reduce emissions..all it did was reduce power and MPGNot knowing which year the car or the transmission is I would think it would be the 4th speed switch to operate the Trans mission Control Spark system an emission system component. If it is has a plug, the system is probably by passed, like most are.
