Subject: Re: firewall boot/grommet for shift rod

Thank you Keith. This 900T is indeed a US spec car--the comes from Walla Walla College in Washington State--and it does have a catalytic coverter. I am certain the shift linkage boot/grommet at the firewall is the culprit. After removing both center consoles and the HVAC duct hidden thereunder, I found the rubber boot with a big gap around the shift rod. When driving at speed, hot air gushes in through this same hole. With the HVAC duct in place on the floor, this hot air is directed smack onto the shift lever housing which gets hot and causes the keys to get hot. I don't know exactly how this boot/grommet is supposed to look when in good shape but I don't think this one is in proper condition. The thing I am worried about in disconnecting things on the shift linkage is making sure I get things back in the proper arrangement. I have found many things out of order after I acquired this car. I know there are changes in the transmissions between 1984 and 1989; an example would be the centering mechanism. Would the Bently 8valve manual be sufficient or would I have to find a 16valve manual? The catalytic converter is something I have thought of but haven't looked at real closely yet. I plan to soon replace the exhaust from the turbo back. That will be a good time to check out the heat shield for the cat.
