I had the 30k service done on my 95 vr4 last week. I specified a trany & transfer fluid change. The next day I noticed hard shifting in all gear so I took the car back. Was told the linkage needed adjustment and they had made the adjustment "so come pick up your car". It's still not smooth like it was before the 30k service. Can the new fluid be causing this hard shifting? This car has never been abused or driven hard and I am the original owner. Is there a special trany lube that may fix the hard shifting? Please help I fear I maybe damaging the trany trying to force it into gear.

I don't know if it's valid for '95's, but it sure helped out with my '91. FWIW, the "friction modifier" I used was the same stuff they use for GM diferentials.

My transmission shifted hard from day one. Finally I mentioned it to the dealer. They replaced the transmission fluid with synthetic fluid. That took care of the problem.
