The car might have an automatic cut off to either disengage the transmission or cut off the engine. Otherwise you will rip apart the transmission.
Your transmission is slipping and needs to be rebuilt.
There are several indicators of problems with a cars transmission. Examples of these include lack of response while driving and leaking transmission fluid.
Transmission Problems, you shouldn't be driving with this on!
transmission pressure control solinoid
when driving up hills at lower speed you must downshift the transmission
put the transmission in neutral and shift the transfer case to 2WD. if the transfer case lever is stuck, try driving forward very slowly (walking speed) then putting the transmission in neutral and shift the transfer case to 2WD while coasting forward. once the transfer case is in 2wd, it may be necessary to disengage the 4wd by driving the vehicle in reverse for a short distance.
The advantage of a six speed manual transmission over a automatic transmission is you control the shifting. Now this can be a good or bad thing. It depends on how exprienced you are at driving and how well you know your car. Another advantage is that when you are driving or racing on a track you have another gear to go unlike other cars.
Driving that vehicle will lead to serious transmission problems in time. Have the transmission fluid flushed and filter changed soon. Next time stop by your local auto parts store and ask for assistance.
If you are city driving, and stopping at many lights. The tranny might be shifting into overdrive constantly for just a few seconds before you have to stop again, which would cause excessive wear on an expensive transmission. Personally, in this situation I would disengage the overdrive.
Yes, under most conditions you can use overdrive. If you are pulling a heavy trailer, or the vehicle is heavily loaded, I would recommend you don't. If at anytime you a driving loaded and the transmission starts changing gears constantly, you should disengage the overdrive.
Gears slipping, such as sudden high RPM's and loss of power while driving. Failing to change gears at a certain RPM in an automatic.
