can't shift from 5 to 4 - upshifts smooth- 5 to 3 ok- any help- thanks

 

does it grind or does it just refuse to go in?

 

Try it at a slower speed - 5th gear is good down to about 40MPH, just let off the gas and let the 5th gear slow the car down and then try to downshift.

Or if you must...let the car slow to 40 and pull it out of 5th into neutral. Bring the engine to about 2200 RPM and powershift it. You might get some unhappy noise but it should synch up pretty quickly.

 

Are you rev matching? Spring centered clutch?

 

Yes, that sounds like a wonderful idea with a tranny that most likely has syncro issues.

 

Since this is a "shifting gears" thread.....

I have an 1991 S2, and a couple of times while hard accelerating there is a resistance to shift into 2nd gear (fast shifting)

1st, acceleration.... push cluch shift into 2nd... then release the cluch pedal (sound from the gears like the second gear is not meshed properly) again pushing of the cluch and then do the same things in a softer way and there is no problem at all.

And i have experienced my self a resistange once, while downshifting (i think it was from 4th to 3rd...)

Do i need to check something on the gearbox? any thoughts?

 

Just bought the car from another Rennlister didn't you? Congrats on your purchase!

It could be a simple fix or adjustment. If this is your first exposure to 944 series cars it might be worth taking it into a Porsche mech. It could be the lever is worn out and needs replaced (along with the bushing and washer) or the mechanism in the back on the trans needs adjusted.

 

What kind of oil is in the box, and how long ago was it changed?
