I have a 1998 Plymouth voyager. 3.3L engine. with a 4 speed transmission.
I have NEVER had any trouble with the transmission.
Saturday - Kept going into "limp mode" about 1 mile from home
Immediatly changed fluid, gasket, screen, ect. (used atf not mercon or whatever it's call) Hubby drove about 5 miles No problems.
Sunday - I drove 15 miles and went into limp mode again. This time the speedometer was flopping all around. Would go to 100 then to 30 then to 0 and back to 100.
I took the van home and parked it.
Wednesday - We put in a new output speed sensor. the only difference is now the speedometer does NOT work at all.
Thursday - put in a new input speed sensor. NO change.
I'm going to carefully and slowly drive to parts store to have it scanned today. The local garage wants $60.00 just to scan it. I just don't have the funds to go there right now and I don't really have the money to keep playing a guessing game either. According to the readout I get today does anyone have any ideas on what could possibly cause this? There is no hesitation, jerking, ect when going into park, reverse, or drive it just does not change out of second gear when you speed up. Other than replacing or rebuilding the transmission the only other things I can think of that might cause this is the transmission control solenoid or the transmission control module. One more question. DOes the computer have to be reset after adding the sensors to "pick" them up? THANK YOU TO ANY AND ALL ANSWERS.
