I have a 99 Nissan Pathfinder. It drives perfect in forward but gives a delay in reverse. In the morning it runs fine but after warm up it does not engage immediately. It moves after giving lot of gas and engages suddenly. Mechanic said it is a transmission problem and will run okay for a while if transmssion fluid is thick. ANy suggestions on how to make transmission fluid thick ? Thanx a lot in advance.
