Trying to put my RB25 tranny back on my RB26 and it won't slide all the way in. I can't get them any closer than about 1".
I'm using a Giken STR clutch/flywheel. I used a Z32 alignment tool. The clutch slides onto the splines off the motor, so I know that fits.
Both the engine and trans are out of the car, on the ground. I've tried it with the trans in neutral and in gear. I've tried lining it up with jacks, blocks of wood, an engine hoist.
I don't want to try and pull them together with the bolts, that idea just sounds like a disaster waiting to happen.
I've tried a light coating of grease on the input shaft.
Any ideas I'm missing?
