Hi, Can anyone help with this? My 1993 auto terrano is over revving uphill when its trying to change down through the gears - It feels like is slips into neutral (the RPM revvs to over 4000) as the truck looses power and speed. Very frustrating! Have been to 2 mechanics who both said different things - one said its the kick down cable, the other said its the torque converter or tramission. Anyone had this happen?? Hoping its an easy fix.....Help!
