I used Pennzoil Syncromesh with great results.
Do NOT use synthetic oil in these transmissions, it's actually too slippery as previously mentioned by AJ.
And that's a pity, I am a synthetic oil type of guy...
This is a Contradiction! You just said "I used Pennzoil Syncromesh with great results"
and "Do NOT use synthetic oil in these transmissions"
What Gives?
I'd like to try the Valvoline Synchromesh... Is it a Synthetic?
No Offense to you DartNut! Just trying to figure this out.
