I have just purchased an AW71L transmission which came off an accident-damaged 940 with about 150K miles on it. It wasn't expensive, and was a fun day out to go and get from the seller, who lives in a remote and scenic area. My question is, should I simply change the rear seal, fill it up with fluid and switch it out for the AW70 in my beautiful '92 240 wagon? Or should I have it rebuilt -- perhaps at least the valve body? The AW70 in my wagon shifts fine, but I do a fair bit of cruising over 50mph, and I like the idea of the lockup torque converter. My second 240, a '90 sedan shifts a little hard from 1st to 2nd, but is only used for dirty jobs/exposure to salt water from Kayaks on the roof. Maybe I should put the AW71L in this one? Its AW70 has shifted about the same for 7 years without getting worse. Decisions, decisions... what do you think?

i would reseal the front of the trans, also. pump seal and orings. good luck, chuck.

If the fluid in the 71L looks decent I'd just go ahead and put it in. I'd put it in the car that I do the most highway cruising. If that's the wagon then you'll have the 70 that came out to use in the sedan should it ever be needed. I don't mean to be insulting but--did you take the torque converter along with the 71L? without that you're back where you started. Also be aware - any 71 shifts harder than the 70. I had a '92 940 Turbo with the 71L and it shifted like the 240 Turbos we owned with the 71 installed in those - which is to say - a snappier, more direct shift than 240's we owned with the 70 -- Dave

Thanks for the replies. The fluid looks decent -- not new, but still closer to pink than brown. I have the torque converter.
