Hi everyone,
Own a 1991 NIssan Pathfinder since 1996, just for regular commuting. Very reliable truck except for the transmission. Had to rebuild it 5 years ago (99K miles). Now it has 188K and i am starting to have transmission failure symptoms. Reverse works but with difficulty at a very low speed any obstacle will prevent it ro run. Forward gears all work fine. In forward the transmission seem to slip when cold, runs fine at normal temperature. I did not flush the fluid since the transmission was rebuilt. Is it a good idea to flush the system now ? i got advice that's useless and could make it worse.
Any advice greatly appreciated!
Have a wonderful day
