Having a Problem....

[Godsson314]

My 92 Camry seems to be burning more gas then it should....it does not seem as thought it switches into a higher gear, (the rpm never goes down though you are accelerating).

Has anyone had this problem before, or suggest somethings to me?

Sounds like you might be having a torque converter issue. Try getting your transmission service at a lube shop.

This may sound stupid and please don't think I am being silly, but have you perhaps accidentally hit the button to switch the transmission into power mode or turn the OD off?

[Godsson314]

Oh...I wish it was that simple with the OD button.......I will try to flush it at a station when I go to retrieve the car this weekend.... I appreciate the suggestions...if there are anymore, please keep them coming.

If it hasn't been done in at least 30k miles then I'm fairly certain it will solve the problem. If not, my next step would be to disconnect the negative battery cable for a few minutes, forcing the car's computer to reset.

I would check the coolant temperature sensor (Toyota calls it an ECT sensor in their manuals) on the car with a digital volt/ohmeter and the specs from any manual. The transmission is electronically controled and it isn't allowed to go into overdrive (your 4th gear) until it reaches a certain temperature. If the coolant temperature sensor is out of range, it may not be telling the ecu that temperature is ever being reached, therefore keeping the transmission from shifting in to overdrive. This would account for both of your problems.

Heh, and I just thought it was a symptom of my Celica getting old that it did that...

I still stick with getting the transmission serviced if it hasn't been done in 30k.

The O/D light can be used to readout any trans trouble codes stored. Download the appropriate service manual section for the link below for details on how to do this.

Yeah, but would a Gen 2 actually store a code that didn't cause the SEL to come on?

I am going tomorrow to check the car out...taking it to get the tranny flushed and pull the neg battery cable. I hope it works, cause it is a great car...Would the o/d read out work? I didnt know it would in the 92.....
