    Re: Trans slipping in reverse

    Dan, before going to the trouble of pulling the unit, I would really try some Red Line MT90. Geo, Randall, and many others recommend(ed) it. Like I said, my car stuck in OD for weeks, but one trip with MT90 solved the sticking problem. Yours is the opposite, but it is still the same part at fault. If it doesn't work you are only out about $10 in oil.

    John,
    you haven't bought any Redline oil lately. I paid $57 for a gallon a few weeks ago

    Re: Trans slipping in reverse

    Yup! I am going to try the oil and see what happens. Going to the rear end shop now. They replaced the bearings and seals. Thank you all for the advice, and of course we all miss Randell"s input!

    Hopefully, the generic trans./shop didn't cause the problem because of not being familiar with the OD. Please let know what caused the issue. Changing the oil can't hurt, but I doubt if it solves the problem.
    The Buckeye article is what sparked my response to your posting. There are a real treasure on all things trans./OD.

    Re: Trans slipping in reverse

    This is 100% a slipping unidirectional clutch. I actually got my car to do this when i set up the solenoid height too high and the internal ball was not totally seated allowing pressure to build in the OD when turning and cause the slip. Yes the clutch springs will get weaker over time but if the ball is not seating properly it will allow pressure to build in the OD and push on the clutch. As long as that valve is closed the springs are not part of the equation, especially if the OD releases properly when driving.

    That's actually a pretty good price. Where did you get it ?

    That is certainly a possibility. I hope that Dan checks the operating valve adjustment and drives the car before pulling the trans.

    Re: Trans slipping in reverse

    As soon as I get the ear end back from the shop and install it I will fill the transmission with the proper mt 90 oil. Then give it a test run. I was promised the rear end by today but no call, I guess Monday will have to do.

    Re: Trans slipping in reverse

    Redline is great and I use/recommend it to everyone with OD. Redline absolutely will fix a sticking sliding clutch but the rollers in the spring clutch act steel on steel which sees less impact by oil choice. The actual sliding clutch is lifting off the rear annulus and allowing the rotation.

    Re: Trans slipping in reverse

    Went to Napa O'riely and the local auto parts store to get the redline oil. No body carries it. Ordered a gallon from amazon, will be at my door tomorrow. Installing the diff. today and brakes flushing out the old brake fluid while I am there.

    Yes I had the same problem with the red line here in a kinda big city. I have not run my OD yet so I did not order any Red Line, and sorry to be so petty, what does a gallon cost with shipping.
    Thanks steve

    Steve $61.50 from Amazon will be delivered tomorrow.
    I reinstalled the rear end today. CFDC9D1F-7846-490B-92C9-DEE177485F2A.jpg I noticed that one of the universal joints was binding a little. Ran down to Napa auto parts and got another one. Installed it on the yoke and axel, (the one near the diff) and the new one is binding also. Ordered a new yoke and universal joint from BPNW, just going to replace it and hope for the best.
