Hard Shifting

Hello All,

My car recently got the tranny fluid changed out to Swepco 201. It was shifting a little rough before and I thought the fluid would change would help. Well it is still bad and getting worse.

The problem:

when cold it doesn't like to **** into and out of 1st, 2nd, and into 3rd. Out of 3rd and into 4th is fine.

When she warms up shifting smooths out considerably. Also I have to be sure to basically stand on the clutch pedal to make the engagement and disengagement as smooth as possible. My thoughts are:

- Shift linkage bushings/shift lever bushings
- clutch master/slave has air
- clutch master/slave is dying
- dying clutch? (it has been replaced with the turbo disc)
- syncros going kaput! I sure as hell hope not!

TIA

Sounds like a disengagement issue. How is the clutch disc?

based on your storymy first suspect is clutch hydraulics. mine has a little play on the rear shift linkage but it still shifts smoothly enough. check the rubber portion of the clutch line for balooning, and verify the condition of both master and slave cylinder first.
good luck!

Do you have the rubber damped clutch? look inside the bellhousing to see if it has fragmented. Sometimes there are pieces floating around in there. Hopefully, it is just hydraulics.

I am going to bleed the Hydraulic system sunday and see if it improves. My natural inclination is to lean towards failing master or slave cylinder as it doesn't do it all the time. No the clutch disc is NOT the rubber one.

FWIW, I changed to the Swepco 201 (when chasing my hard shifting) to Redline MT90. The MT90 improved the shifting , the real issue was the clutch disengagement. I swapped the clutch, PP and flywheel out and it cured my shifting issues.

I replaced the rubber clutch with a conventional one, drained and replace tranny fluid with redline MT-90 and getting ready to install the new short shifter from online944. Shifting is smooth. Sounds like clutch or synchro's to me.

Some people try to turn back their "odometers." Not me. I want people to know 'why' I look this way. I've traveled a long way and some of the roads weren't paved.
