If it's an automatic, probably an electrical fault in that circuit. If it's a manual , more than likely bent clutching teeth on the 4th/5th synchronizer. I have an 89 auto that had a symilar problem. It was a blown thermostat. EXACTLY. If the vehiicle does not reach a certain temperature the trans. wont shift into overdrive. I had this problem years ago and it took 3 genius dealers to figure it out!!!
I have a 1989 Dodge B250...it has overdrive
Overdrive should be ran by electrical ,so check your fuses . If that's not it check wiring that runs to transmission.You will have to get under the vehicle . There is an electrical switch that shifts the trans into overdrive , that is your next step . If you have a owners manual in the glove box it should tell you which fuse runs the overdrive circuit .Hope this helps . Rick
There is no direct fit.There is no direct fit.
Behind glove box
Should be the same
getting ready to put the motor from my 1989 Trooper into a 1986 Trooper II... will let you know how it goes!
There is no separate switch for the overdrive, simply put the gear selector in the overdrive position. It looks like a D inside a square. Not all Chevy Celebrities have the overdrive feature, it was an extra cost option.
i cant find the color code for my 1995 Isuzu trooper CD cassett please help
The factory sticker on mine says it should be .008 on both intake and exhaust.

Yes I just did that to mine, and it works great. No problems.
The rims match an 89 Nissan Pathfinder for sure.
If it was a manual trans it was a five speed. If it was an auot then it was a three speed with an electronic overdrive. So with the electronic overdrive it was a four speed trans but the overdrive failed frequently and was disabled by many owners.
First the gear could be out. The other issue could be with the linkage itself in the transmission thus it won't go into overdrive.
mabye u need to make a gear adjustment
Most likey its the TH400. If it has 4 speeds, its the 700R4 (w/overdrive)
No overdrive but the non turbo 4cyl had a lock out torque converter that usually kicks in at about 46-48 mph. Gave an extra 2+mpg. Not available on turbo cars.
Locked forever as in abused or worse? Not enuff about it to get a competent answer.
blown head gasket
on the shifter the left hand side just under the shift button.
What motor is my question. it's either the 2.6L 4-Cylinder or the 3.2L V6 and having owned 4 rodeos and 2 Amigos (as well as 1 trooper) I know that the rodeo was first introduced in 1990. again, the 2.6L 4-Cylinder or the 3.2L V6 are the only ones that would fit.
