AW70 leaking 200 1991

Once again trying to diagnose the kid's '91 244 from across the country... It recently started leaking ATF from what appears to be the transmission oil pan on the passenger side. He got a new gasket and although was unable to remove the dipstick tube, he had enough clearance to get the old gasket out and the new one in. He did note that one of the forward pan bolts on the passenger side was broken off, but supposedly that's not where the leak was. With the new gasket in place, now it leaks from 2 places on the passenger side. I'm trying to keep him out of an Aamco-type money pit!

Is there a more likely leak source on the passenger side which he just can't see easily?

Is a dented/deformed pan a likelihood? If so - what's the best way to find a replacement?

Any other ideas?

Of course he doesn't dare drive it until the leak is fixed... he knows he can burn up the trans if he runs it dry.

Thanks all, in advance...

    More information... seems that the trans mount failed some weeks ago, and before it was replaced the trans was banging on the crossmember. Maybe the pan is deformed...

    Could be leaking from the shift shaft seal on that side, the O rings underneath the trans cooler line fittings on the side of the trans or the cooler lines themselves.

      I've seen 2 in the last week where the selector shaft seal on the passenger side (just above the cooler line fittings) slid out of the bore partway then cocked sideways - one on my girlfriend's car, one on my mechanic's car. Never seen it happen before, then 2 at once... Seems like it may be contagious - I'm quarantining her car from mine now. In the absence of having replacements in stock we opted to gently tap the seal back into place. The dripping has stopped but I'm sure it's just a temporary fix - the replacements are ordered. Replacing the seal will involve removing the top cooler line to allow a socket to be used to press the new seal squarely into the bore, otherwise seems straightforward. Best of luck!

    Hi Smitty:

    Could be the leak source is from one of the steel lines that run from the trans to the radiator for trans cooling. They are attached to the side of the trans by a metal clamp that does over time rub through the tubing causing a leak down the trans on the passenger side. New lines are available. As a temporary repair you can cut the line and splice in a short piece of rubber tubing, should be about 5/16 and secure the tubing with two metal clamps. Hope this helps.
