95 Jeep Grand Cherokee not shifting into overdrive
Transmission not shifting into overdrive, running high on RPM's, BUT not all the time. Sometimes it does, sometimes it doesn't. Could it be an electrical Module that is causing the transmission not to shift into high gear? Had the transmission checked out several times without going inside it and they say it is fine???

Re: 95 Jeep Grand Cherokee not shifting into overdrive
Does the O/D OFF light come on when the transmission does not shift into OVERDRIVE?

Re: 95 Jeep Grand Cherokee not shifting into overdrive
No, the tranny is prolly overheating. When the transmission overheats, the TCM shutsdown the OVERDRIVE to reduce the heat in the transmission.
1st thing I would do is check the tranny fluid level. Then, maybe have the fluid and filter changed along with a Flushing. |

Re: 95 Jeep Grand Cherokee not shifting into overdrive
Viking I have the same problem with my 95 JGC. If you find out what the problem is, be sure to post it. I think it may be a module too, I changed the 10 and 15 over the weekend but it didn't improve. I don't think the tranny is overheating either, because it usually does it when it first starts up after it has been sitting for a while.

Re: Re: Re: 95 Jeep Grand Cherokee not shifting into overdrive
sounds to me like the TCM or the temperature sensor, I have read on here when the problem is related to cold it can be the temperature sensor.

Thermostat
Ok, I know this sounds weird and I didn't believe it when I was told by a friend at a transmission shop, but he told me to change my thermostat. So, I did just that and it lasted a year! A year later, O/D wouldn't work again (in cold conditions) so I changed the thermostat again and it solved the problem. Apparently, the transmission is temperature sensitive. Try it! It's a cheap fix and it worked for me!!

Re: 95 Jeep Grand Cherokee not shifting into overdrive
Please let me know what fixes this tranny problem. I have sort of the same problem but mine won't shift into overdrive or won't start out in first sometimes. Sometimes it starts out in 3rd and that's it Thanks and goo luck. Rob

Re: 95 Jeep Grand Cherokee not shifting into overdrive
$300 to change a T-STAT is crazy, the Thermostat only cost about $10-$15 (AT THE VERY MOST) and you could change it yourself within an hours time.
