1991 Toyota Corolla Q&A

1991 Toyota Corolla Question: what is the problem when the transmission will not go into reverse.

all forward gears work fine, But when I go in reverse you can hear the engine idle drop like it is in reverse car will not back up. I let the car sit for two days after I changed the filter and fluid thinking that would solve the problem it didn't. I checked the car again ( after the two days) transmission goes in reverse strongly no problems. Drove the car in reverse for about a 1 block down the street worked fine. backed the car in the yard shut it down. 30 min. later no reverse. is this a computer issue or a valve body issue. please help -
