I have a question for the transmission gurus on FABO. I rebuilt an A999 last year. First one I ever did. I read the usual books etc. I installed a a TF2 kit and drilled the holes about midway through the recommended range. I also installed a Sonnax upgraded accumulator and Transgo accumulator spring. Last fall the transmission started to whine in 2nd. It seemed to be from the valve body. It got a bit worse over several weeks and then the transmission started "braking" in second. I assumed that the trans was in two gears at once so I parked it for the winter.
Last week I dropped the pan and the valve body. I didn't see too much friction material or glitter in the pan. However I had use a pair of channelocks to get the accumulator out. I also noticed significant wear on one side of the bottom protrusion of the Sonnax accumulator. The hollow cavity on the top of the accumulator was full of black/gray gunk. I'm assuming it is friction material. When I re-installed the accumulator it was tight but moved up and down. I could move it with my fingers. Then I pushed it the whole way up into the bore, met some resistance and heard/felt a loud click. I needed the channelocks to remove it again. I had to use pretty significant force to remove it. I did not see any damage to the bore or the accumulator.
I would think that the hydraulic pressure would be enough to force it out of the bore and against the spring, but maybe not?
My questions are: Would the accumulator being stuck in the "up" position cause and overlap condition that made the transmission feel like it is "braking" in 2nd? What would cause the accumulator to get stuck in the bore? Thanks!
