Re: Ultramatic Hard Shifting into Reverse

Thanks for the thanks but I don't think that the 10 degree lash in your rear axle is the cause of the rough shift from fwd to reverse. It is well below what I have experienced in smooth shifting cars. Also, the rear axle is not affected by warming up and getting looser, it is a pure mechanical connection.

My guess is it's in the trans which can be affected by temperature. Some operating seals in the reverse piston servo are rubber.

good luck.
