Question about 1999 Plymouth Neon

1 Answer

Transmission slipping...... I just bought a 1999 Plymouth Neon Expresso and I am having trouble with the tranny. It is starting to over rev when I shift gears(automatic) and I think that I have a leak in the main seal.... This would require dropping the transmission which I have heard can be pretty difficult for a front-wheel drive car.... I would like to know how much I shpuld expect to pay and if that is my problem..... It is leaking Tranny fluid, but I do not know from where yet. the previous owner gave me the tip-off about the main seal.... Any suggestions?

If its the main seal gone,you will have to remove the tranny regardless because the main seal is the torq converter seal.Even though it leaks,if its slipping when full of oil chances are your tranny is no good,if it shifts fine its not to late,just keep it full of oil and have the leak fixed.Look under the front of the car when its in park,with the e.brake on and running,look for the leak.If the leak is between the the motor and the tranny its probably the main seal.Check the transmission pan,axle seals and coolant lines for leaks also.Changing the transmission is no small job and should be done by a garage if your not sure how to do it.Hope this helps.

Not shifting


Any transmission trouble code will put the trans in second gear
and it won\'t shift.
Key on-off-on-off-on without starting the engine will illuminate
the check engine light .It will flash out the codes.Should see a 55
code ,5 flashes,a pause then 5 more. Any codes other than 12 and
55 need recorded for further diagnnosis.
I was thinking that turning the key on and opening the throttle wide
open 4 times within 5 seconds (engine off)clears tranny codes,not sure about that tho. You might try it then drive it and see if it shifts,although
as soon as the malfunction happens again it will go back into limp mode.
Tranny slipping or a slow shift or converter lock up malfunction along
with many other things will trigger this.

Voyager transmission problem


Sounds like you need a solenoid pack to start, and possibly a service. If the tranny is not slipping, the solenoid pack is stuck and not tell it to shift up. Could possibly be a TCM, but not as likely.

97 Neon Expresso, Schreeching Fan


Both your air con and defogger (I am assuming you mean front windshield defroster setting, and not the back window) engage the air conditioner pump/compressor.

The screeching can be either a bad belt or a bad compressor.

How long has it been since the belt was changed? If it is old, and slipping, it will cause the screech at speed.
If the belt has recently been changed, and is adjusted properly, I would start looking that the air compressor pump.
