SVX Tranny
 

Hi!
I am also a mechanic (Toyota) and I had a wierd hair and decided to convert my 94 L SVX to AWD. I bought the stuff from a salvage yard I sell parts for. I got it all together and everything works (I made some additions to the wire harness for the FWD and AT OIL TEMP light) but the awd is messed up. The car will spin the front tires noticeably and then buck, at witch time the line pressure at the extension housing momentairly shoots up, then immediatly drops off. Needless to say there is something abnormal about that! I followed the diag tree in the service manual and it led me to duty solenoid c, but I also read a TSB on the seal rings in the extension housing(you know, the one where it cuts into the extension housing). My tranny number says it should have the new rings, but it sure seems like they are my problem, and a former Subaru master tech I work with told me they were the cause also. Any help would be appreciated!

Thanks,
Nate
