Try changing the fluid and filter.
If it's an automatic, you may have a sticking solenoid INSIDE the transmission.
if it is automatic the transmission could be slipping if manual the throttle could be sticking
EITHER NEEDS LINKAGE ADJUSTMENT OR TRANSMISSION OR MOTOR MOUNTS COLD HAVE SHIFTED.or wrecked.Or THE DETENT in the trans is sticking
sounds like the torque converter needs repair.take it to a good transmission shop
Most usual reason is the ignition module in the distributor, or it could be the float needle sticking if it is the carby model.
Automatic trans. on Neons used to have problems with the solenoid packs sticking. Check to see if you have a transmission controller code. If it has a code for L/R solenoid stuck in L or R poistion, put a solenoid pack in it. It might just be that the trans needs to be overhauled.
sounds like one of the valves in the valve body is sticking when it gets hot (metal expands). Sounds like a Ford automatic overdrive to me.
If the idle is set too high, and you have an automatic transmission, this will happen. A sticking throttle cable or rod can also do this.
Your transmission is "sticking" sometimes a fluid and filter change can resolve this problem for a short time however is this does not help there is a solenoid in the trans that needs replacing any transmission shop can preform this solenoid swap relatively cheap and most have the capability to diagnose this problem for free
Under the hood, inside a tube, sticking out of the transmission
If the vehicle has an automatic transmission, then the torque converter clutch is probably sticking. The clutch is controlled by a solenoid, that moves it back and fourth. The clutch material can get stuck to the inside of the converter and stall the engine. Have the transmission flushed, and if the problem persists, then have the solenoid replaced.
No... 1999 to 2001 will work only for those model years. we tried sticking a 98 into a 2001 and it fits but won't work because of the sensors
