[Fot] TR6 transmission rebuild - counter shaft gears

Mon Jan 8 14:21:10 MST 2018

Ok. I asked about withdraw of the rear thrust washer up through the case because it looked to me that this would work. I had a good shot at it with a punch trying to drive it up and out and I was not making progress. The tab is correctly aligned (not spun). 

It maybe that the centerline of the lay gears was slight off center while I was whacking away at the thrust washer. I'll try again by getting the lay gears back in alignment and then attempt to get the washer out. 

Thanks for the input guys.

The lay shaft has to not be jammed into the car, but the bearing surface between the first gear end of the layshaft and the case will allow the thrust washer to come out as long as the tab is in the groove in the case. If that is not your situation, then you need to try to spin the bearing around. Note that it is pretty hard to get that rear thrust washer oriented incorrectly, but it can happen if the thrust washer spins in the case.

I was able to get the washer in a position to grab it with a really small channel lock plier and pull the washer out. Others already commented on making sure that the lay gear isn't cock-eyed in the case.
