If you are up for some repair work, a possibility would be to take the main mechanical section out of a transmission of a later vehicle....I would suggest a Land Rover Discovery 1, 1996-1999 that has all the bugs worked out of it, and swap it into the case of yours, keeping the valve block, governor and torque converter all the same the original. The 4HP-22 transmissions all use the same main mechanical section, clutches etc. Its actually not a very difficult job though having the Volvo green book is an absolute must.
Of course I should also mention again that I have a good one in my garage......but its a very long way from California.
If you have debris in yours, make sure you have the torque converter cleaned out.

I still owe you info about where transmissions might be found in California... look for a PM.
