The trans in your truck had some problems in that era with overdrive. You will need ot check a few things to be sure it is not internal. The overdrive would often fail in those units due to the o rings used instead of lip seals.

Check the temp sensor. If it is bad the trans will not go into od. A defective solenoid in the trans for overdrive could cause it not to go in.

Check the fluid, if it is black, you may have burnt the clutches. I have know people who have driven the toyo's for years with no od. It is the same as the old three speed auto.

Hope this helps

SOURCE: 1999 ram auto trans wont shift into park

you could need a throttle linkage adjustment. first check to see if your ram will start in "park" and "neutral" only. if it starts in any other gear=faulty neutral safety switch. replace. ok, now check linkage for proper adjustment...with engine off and in park...remove intake housing..disconnect cableend from attatchment stud on your throttle body..slide cable off the stud (carefully)..verify that the transmissionthrottle lever is fully forward (idle) position..and verify that the lever on the throttle body is at curb idle pos..insert small screwdriver under edge of the retaining clip and remove..center the cable end on attatchment stud to within 0.04", or 1mm. install retaining clip onto cable housing..check cable adjustment..be sure trans throttle lever and throttlr body lever move in sync with each other.

I have an 1988 f-350 diesel with an auto the trans is new but wont shift into overdrive,first and second and third shift really firm but just wont go in fourth


Its NEW? take it to whoever you got it from. The problem may not be IN the trans, but a trans shop need to check it out to see why its not going into overdrive.

My 1991 sonoma 2wd auto will only has low gear and reverse. Trans fluid looks ok. What could the problem be.


You broke the low one way clutch. The trans will need rebuilt. The truck should be drivable if you take off in Man 1, shift to Man 2 at about 12mph, then shift to drive at about 27, then shift into overdrive at about 42.

Takes a long time to shift into overdrive


sounds like the toque converter is locking and unlocking have the trans serviced and flushed if this does not cure the problem then you could be looking at a trans rebuild or replacement.Check the fluid first could just be low.

How to use the overdrive on the auto.transmission.


the overdrive button on your automatic transmission is for cruising on the highway basically like having another gear for better economy careful not to use it when your not on the highway because lugging the car in overdrive when its not needed will cause higher fuel consumption other than that you should have no problems just get out on the highway and push and away you go

NO OVERDRIVE


Toyota ed is right when he speaks of low coolant temp as a cause. there is also a temperature sensor on the engine that is specific for the auto trans model. may be a white plastic single pin connector by the t-stat housing, not to be confused with the blade type connector that is used for the temp. guage. were you sure to connect the connector that powers to o/d solenoid on the side of the trans. when you installed the engine?

1991 toyota 4runner sr5 3.0 v-6


i had the same problem after spending $500.00 for toyota to look at it they didnt fix it and suggested i it was the auto trans and i should get it overhauled costing thousands. i didnt believe them and started to do some of my own research into the problem. the coolant temp sensor at the rear of the intake manifold tells the ecu when the engine is at correct operating temp then allows the auto trans shift into overdrive. to rule out any problems with the auto trans i disconnected the plug to the temp sensor and went for a drive when the engine was cold and it shifted straight away into overdrive no problems. you can't leave this disconnected because the engine is hard to start when cold as the temp sensor also tells the ecu that it is cold and allows the cold start injector to inject more fuel into the engine on cold start up.to overcome this i cut the wire to the sensor plug and installed a switch which i installed into the centre console.now i start the car flick the swith use overdrive then swith back to normal after car has warmed up . engine fault light appers on dash when switched on but doesnt matter. i have had this modification for 2 years now no problems.
