I have the original Muncie 4 sheep transmission in my C2. The shifting is tight and is difficult to get inton reverse. Is there anything wrong with this and/or can it be fixed? As always thank you fro your input!

Re: C2 shifts hard
The clutch may be dragging. Check the freeplay. It may be excessive. I believe the spec is one inch with the clutch linkage set at the standard ratio and about three-quarter inch with the linkage set at the "fast" ratio.

Re: C2 shifts hard
John-I had the same problem last year with the Muncie in my C-3. First, I would make sure the shifter and clutch are adjusted correctly. My transmission had some miles on it anyway so I removed and rebuilt it. What I found inside convinced me I did the right thing. I found the shifter forks a little worn and sludgey congealed gear lube. Upon disassembly of the main shaft and gear set I found the same sludgey old gear lube under the sliders. After a thorough cleaning and replacement of bearings, shift forks and assorted small parts the transmission shifts smoothly. The GM Overhaul Manual walks you through the process nicely. Good Luck!Comment

Re: C2 shifts hard
Chuck, Did the rebuilding of your Muncie require any special tools and did you find the job fairly straightforward? I have opened mine up and I see it needs syncro's, and at least one new shift fork.
Thanks, Scott MarzahlComment

Re: C2 shifts hard
Scot-I had access to a press for disassembly and reassembly but found no problem during the disassembly as far as parts being excessively tight. During the reassembly a press would make it easier. For reinstallation of the"cluster" your would need a dowell the length cluster and slightly smaller in diameter than the cluster shaft.I made a "dummy" shaft out of mild steel but I can remember people using wooden dowels in my younger days (teenage). I feel if your have average mechanical skills you can rebuild your muncie. I enjoy working on my car as much as driving it so a project like this is fun to me. Scot-Good luck.Comment
