need help with shifting and vibration. wont stay in first but if you hold it there it will think it is a syncro. other is vibe at around 55 mph range comes from rear maybe center of car. I had a 86.5 5-speed but never rn into these things with it now I got a 87 N/A 5-speed runs much better than my 86.5.

For the "won't stay in first" gear, open up the boot and remove the other rubber boots and see how the shifter fits into the rod end. There is a little plastic cap that goes onto the bottom of the shifter which sits in the rod end of the transmission. That rod end also has a bearing pressed into it which could be worn or missing. If there is any sloppiness in the shifter then the parts I just mentioned will be suspect. If its just the plastic cap then thats an easy fix. The rod end bearing is another matter. I had to have a custom made piece that dropped in instead of the bearing which would require tearing down the transmission and replacing the rod with the pressed in bearing.
For the vibration your center bearing on the drive shaft is probably shot or
the universals but more likely the center bearing. When mine went it was slapping on the floorpan when I accelerated.

With my 86.5 supra I had to replace the little bushing on the bottom of the shifter so that was the first thing that I looked at but I didnt know there was a bearing down there. But further details on the shifting problem it will pop out when you get it in gear but if you hold it its fine but if you try to down shift to first from any other gear while the car is moving it grinds unless you double clutch which was why it thought it was kinda funny. With the vibration I was dreading the thought of it being the center bearing it is kinda pricy but I got to do what I got to do. I thought at first it was the diff but didnt even want to get envolved with that have the tools and the knowledge of how to rebuild it but not the time to do it. couldnt beat it car runs real good and the body is real straight but the only things I listed were the problems and I only paid 800 bucks for the car. Thanks for the help though I will look at those things when I get the chance.

Its more like a cap pressed into the yoke than a bearing per se, the hole diameter is for the plastic cap to fit. Mine kept popping out till I had the part made by a machine shop and dropped it in. Also while your at it, change and bleed the fluid in the clutch master cylinder. You can look down from the master cylinder and see how far its engaging the clutch before and after a good bleed. Takes two people though.

If you still have access to the 86.5, get the trans out of it and put it into your new one, that's if the old transmission worked ok.

Just a thought.
