Toyota Hiace automatic transmission
My 1991 Toyota diesel hiace van doesn't shift gears when I put it in Drive first thing when it is cold. Second and first gears work. If I pull over and restart my van the shifting works fine. I just changed my ATF and filter. Am I doing more damage to the transmission if I keep driving it? Any suggestions on problems?
I replaced the transmission fluid and filter after I was getting these symptoms to see if it would help. I will check the fluid levels again. It only seems to happen when its cold and not every time. The mechanic suggests that it would require a rebuild but doesn't have the equipment to test a transmission on a right hand drive. Wondering if there are other diagnostics available before I go down that expensive road.
