67 shifter adjustment problems

Re: 67 shifter adjustment problems

Hello Henry;
The "Honor Flights" are the well deserved by the "greatest generation" and extremely moving.

As a gear GL4/80w90 lubricant I personally use synthetic GM Part
12378261.
Think that's the current number.

You are right about the Honor Flights Ray. The Central Illinois Honor Flight just returned a couple weeks ago from taking their 1000th WWII veteran to see the Washington DC Memorials. The guy that started the Central Illinois chapter, Don Niehart, is one of the most humble and down to earth guys you would ever run into. He has poured his heart and soul into the program. The fundraiser we attended Monday in Effingham was outstanding!!

I stopped into the local Chevrolet dealer today and picked up some GM 89021671, which is suppose to be GL4 according to a couple other Chevy forums. I got it changed out and see if there is any difference. I did notice when I drained the transmission the drain plug had some super small metal flakes. Appeared to be metallic looking so I would assume it was the brass. Both the drain and fill plug were magnetic and had little screens on them, which I assume they were suppose to be. Thanks again for posting Ray. Now I am going to start another thread to identify these parts: DSCN3507.jpg

Hello Henry;
Are you sure you a M20 transmission? Only "rock crushers" Muncies have drain plugs.

Ray, according to the numbers stamped on the side of the case (P0M11B) it is a 1970 Corvette M21 transmission. Would that one have drain plugs?

Hello Henry;
You did state those date numbers earlier in the thread, I had forgotten.
Maybe a C3 guy will chime in here. If not message Terry M. He will have definite answer.
