I seem to be having some transmission problems recently. I have a 92 XJ with the 5 speed. Accelerating I am able to shift regularly at low rpms, <2000. At rpms 2000+ and any deceleration, I can still shift, but it is very hard to get it to shift into the gears. When the engine is off, I can row through the gears no problems. I was thinking that I may have had an air bubble keeping the clutch from disengaging completely, but I rebled it and didn't see any air come out. I searched around and couldn't find a single thread about people having trouble with their 5 speeds.
