The transmission on our 1992 960 has been causing problems for a long time and no attempts to fix it have really worked out very well so I'm starting to look into a replacement. I see both the same and similar years for sale online but what should I be looking for?

I plan on also replacing the PNP, but should I also try and replace the transmission controller with one from the same year as the new one or does it not matter?

Any tips for doing the job? I assume the car will need to be higher in the air than what ramps can do. Not looking forward to that part.

Hello, Just find a low mileage tranny from any year 960 or s-90, v-90. They all work. The NSS can be taken apart and cleaned. I use 1500 wet sandpaper and make the little contacts flat again. I clean out all the old grease and use a good silicone grease or dielectric grease for all the moving parts. Transmission should be drained, converter drained, use grey silicone for the pan gasket and refill with a good dextron three with a pint bottle of red lube guard. Wait until the transmission is warmed up and check fluid and top off to hot mark. Before hooking up cooler lines run a quart of clean fluid through to flush cooler, just in case any debris from old tranny is inside. In 18 years I have only seen 1 controller go bad and it had corrosion on the connectors which interrupted a ground path.

Thanks. I have already cleaned the PNP once that way but it still acts odd from time to time. May have another go at it, at least it's easy to access.

I read the FAQ but one question it didn't answer was how high up the car has to be lifted for the transmission to clear the car? My jack stands have a range up to 21", is that enough?
