auto transmision problems
98' A4 w/50k mi. trans works fine except....no compression! down shift out of o/d and the rpm drops to idle, with car costing like it's in nuteral. Throttle up and when it matches speed it takes off? Am I looking for a new transmission already?
Anybody have this problem? Anyone know how to fix it?

Call a tow truck and get it taken to a good transmission shop. A $50 wrecker bill is cheap compared with a $2,500 transmission.

It could be a problem in the valve body (4-3 valve stuck, mis-positioned checkball or damaged gaskets) which means it could be fixed without removing the transmission. It could also be the input clutch assembly in which case the transmission would have to be removed and disassembled.

if the 4-3 valve was stuck, wouldn't that cause downshift problems? I don't think the tranny has ever been touched, (checkball, gaskets?)
