1991 Toyota Camry Automatic 4 Cyl. Transmission Slips

It is not a suggestion, but just a mentioning of my Camry 1991 that, in 1995, had the same problem. It is possible that was the first model with electronic control of the transmission. I admit, I am the one who made the mistake. It was my first automatic car (presently, I still have manual drive) and, I did remember to change the transmission oil at 50,000 miles. It had the same behaviour and it did cost (in 1995) $1500 at Mr. Transmission. Within one month I took the car, back, two times. I sold the Camry and the lady who bought it came to me after few weeks. Luckily the car was under warranty. Otherwise, when the transmission was functional, it was a pleasure to drive it.

BTW, Camry 1991 and Lexus 1991 were absolutely the same (V6 was standard on Lexus, as well as leather seats).

Sorry I don't anything of your model, but i hope the link below helps.

It's possible the bands that control the gear change have stuck. i would suggest you get the valve block cleaned or possibly replaced.

But i am sure there is someone on here that can help.

Good luck.

It sounds like a similar problem I just fixed on a 1992 Toyota Hiace .

What we did to remedy it was , drained all the fluid . pulled the pan off ,

removed and cleaned the pan filter , then re-installed it - It was full of

soft , gritty trans clutch material. The original equipment fluid was then replaced

with Type F ( Ford ) fluid . This stopped the slipping . Your clutches are wearing down. This is all you can do until , eventually , they are gone , and need replacing .
