Unhappy 91 MR2 shifter problems need advice.

It would seem I have a problem with the wife's MR2.
Car runs fine but after driving it for a while it does not want to shift up or down. The clutch is good on the peddle with no slippage at all. I replaced the bushings at the trans with solid one and also the shifter mounting bushings.
Is it possible that the shifter itself is toast? Perhaps I should check the hydraulics? No grinding or any other noticeable problems.
Any help is greatly appreciated.

So basically once the car gets warmed up it starts not shifting. I would start by checking the master cylinder and clutch fluid levels

Checked master fluid it was fine and have 1/2" travel at trans actuator.
Not sure if 1/2" is sufficient.

Is 1/2" travel enough?
No other experiences with the manual like this?
WOW Her car must really be unique.

Gen1 Maybe a disc problem.

Jeez..ditto with my wife's 89 S/C? pulled in friday said she had to turn off car to get it in 1st, super hard to shift gears without RPM matching (she's my co-driver too).

Like yours, no fluid problems, throw-out bearing and lever seemed to work just great.

Turns out the clutch disc hub was moving ever so slightly inside the disc itself. The rubber plugs used in the OEM disc center section to take up starting forces had hardened and shattered over 2 decades! and allowed all this movement. (doesn't take much)

Since our cars are S/C'd it was no fun to drain the tranny and pull the axles but I found a defective axle bearing in the process and consider myself lucky I was able to take care of both problems at the same time.

BTW be sure to get a disc with springs in the center of the disc, if you want hi-perf? get the type that have dual springs.

Ive never done the clutch on a MR2 before. I guess dropping the engine cradle is necessary to do the clutch or can it be weaseled out somehow?

Don't pull the engine-tilt it

I tilt the engine on the front (pass side) motor mount. I use floor jacks to move the tranny around after and during the lowering. Block the engine in position at the rear of the oil pan.

Pull the entire drs side wheel assembly out of the way, you can leave strut.

Confirm all connectors to engine, tranny etc are loosened. Pull shifter tree, shifter cables, afm and starter.

For me this is easier than pulling the engine.

Are you having problems shifting?
If not, it sounds like your clutch is slipping. How many miles on it?

Hmm? The clutch should still be good, but then, it depends how it has been driven or abused . How far off is it?
