The task to get your OD working again involves removing it from the transmission. The actuating piston O-rings are only accessable with the OD off the tranny. Another solenoid would only cost you money that you do not need to spend.

You could go with another OD... but once you have the OD off the tranny to change in the new one, the replacing the piston O-rings would only take another 15 minutes to the task of swapping out the OD. And two O-rings and a gasket minimum are a lot less than a used OD which may or may not work as a bolt up wihtout some work before hand.

Your OD works and has reverse, if it makes no noise, refurbbishing the one you have is best economically.

Finding a tranny shop that will work only on the OD? Few and far between and they had better be familiar with the Laycock OD's. Ask if they refurbish Laycock Overdrives over the phone. That alone will save you a lot of driving. I hope your fingers are up to punching a lot of buttons.

A better system that would yeild faster results is finding a Volvo specialist that has worked on the Laycocks or find a Triump or MG mechanic willing to do the task. Laycock is British and was used on a lot of the British autos in the late 60's up to when they all went broke in the mid 70's.

I'm obviously not Duane, but I'll bet a good Euro tranny shop already has that pin wrench for dropping the three caps out, and maybe even has the o-rings in stock or knows where to get them easily. For an hour and a half (best guess) of their labor, you could be back on the road and smiling, rather than grunting around with a replacement OD of perhaps questionable merit on your garage floor. Just my $.02.
