I have a problem in my 94 SSEi with 174k'* on it. It doesnt shift into OD and sometimes when it does, if i just touch the gas it will come out and wont engage unless i take my foot off the pedal and am not giving it any gas. Then if i just give it a hint of gas it will come out of OD and wont go back in until i am not giving it any gas. Its more like ODcoast gear... Actually i noticed if i drive anything other than grandpa style, then im screwed out of overdrive until the car is off and has a chance to cool down a bit.. Also, when driving on the highway, and i am accelerating, and let off the gas, the RPM gradually decreases from about 3500-4000 down to about 1400 (which takes about 3-5 seconds which is pretty long i think) where it will suddenly drop to about 600rpm and quickly go back up. Kind of like it wants to stall but has not stalled. -- There are times when all of this doesnt happen, like when its a new day and the car is driven very very calmly..
I also have a SES light on as of last night, and the Traction Off light came on when i started the car back up to see if the SES light would go out, and neither will go off.
The RF wheel bearing was changed and before it was changed the ABS and TCS lights came on and wouldnt go off but after it was changed, this problem did go away (minus the overdrive)
I checked the engine oil levels, seems normal, oil is going to need a changing as its starting to get a little bit brown. There are no strange smells coming from it, and no strange sounds (that i have noticed).
Does anyone have any suggestions or ideas of what may be the culprit??? What can i do myself to see what may be the problem? I will probably take it in to get scanned sometime today if there is nothing i can do myself. Any help from anyone is greatly appreciated!
