Re: New Clutch Inconsistent Shift
Thank you for the reply
Called mechanic he says he followed recommendation and says it was likely kendall 75-90 .... any recommendations on that?
In the initial time after install, 1st, 3rd and reverse were resisting shift.... definitely worse off than the previously installed clutch.
Took it back for some attention and the mec pumped the clutch and it looked like he was trying to eliminate air in the lines but found non. Then he made another adjustment in the gear box and sent me on my way. Was great for a while but now it really refuses to go into 1st at times and I really have to fuss with it, which is obviously disappointing.
Before the update, the clutch pedal used to clip and make a snapping-like sound. That has gone away after new clutch and slave cylinder replacement but now 1st is so unpredictable and mediocre.
Thank you
Re: New Clutch Inconsistent Shift
These older transmissions use "soft yellow metal parts" and some gear oil will not play nice with them. If you're using a std type gear oil, make sure it is GL-4 or GL-5 compliant. If you're using a synthetic, make sure it says it's "synchro safe" for transmissions with "soft yellow metal parts" as the synchros are particularly vulnerable to the effects of some GL-5 synthetics.

If it's not a gear oil induced problem, then it's likely a mistake made somewhere in the mechanical work you had done. Good luck on getting it sorted out. Tim
Re: New Clutch Inconsistent Shift
Tim's advice is spot on and needs to be investigated
Kendall carries a couple of variants but they all carry the following disclaimer
Perhaps I haven't hit on the right product but I couldn't find any without the following info.
From Kendall's site
Applications
- Service fill of conventional differentials in passenger cars and trucks
- Top-off only of limited-slip differentials in passenger cars and light trucks (1)
- Service fill of differentials, final drives and transfer cases in some off-highway equipment
- Non-synchronized manual transmissions in trucks, buses and heavy equipment where the manufacturer specifies an API GL-5 or MT-1 gear oil
(1) Note: For complete drain and refill, many limited-slip differentials may require the manufacturer’s specified gear lubricant or supplemental additive. Refer to the owner’s manual for specific requirements.
Re: Manual shift issue; hard to get into gear
I had similar issues and I adjusted the push rod of the clutch master and now shift beautiful like brand new.

I found this bit of research that might be of interest. It's a study of gear oils sponsored by Amsoil:
