a jeep lumina?
wrong forum but that is ok, seems to be common here.
what wont shift.
A/T or M/T auto or stick? tranny????
what does will not , mean?
I cant move the shift lever
i cant shift, to 2nd
IT (autobox ) will not shift ever, or slips or flares. or?
if its and A/T autotranny, tell me what it does right and wrong
here is an example.
i start engine.
i shift to drive car dont move, in any gear
i see RPM race high with right foot over 3000 RPM.
tranny failure. (slips)
or RPM stays near 1500, and engine sounds loaded,
and i find the parking brake stuck on, or the brakes are full of ice
and stuck fast.
Depending on what gearing setup the car was originally put on, most cars that I have owned that were automatic shifted between 3000 and 4000 RPM. My 97 Ford Escort ZX2 needed to shift around 2000 RPm from 1st into 2nd, but it was a manula which allows you to feel the point of shift alot better. maybe have your onboard computer checked and tranny serviced.
Hello,well at what rpm it shifts at of course depends on how hard your pressing the accelerator at that moment,if you floor the accelerator it will shift at higher rpm (red line) but if you take off very slowly it should shift at a much lower rpm....but to answer your question 3000-3500 is a good shifting rpm( if the gauge red lines at 6000-6500 rpm) and firm shifting is a good thing,slow,sluggish and hesitant shifting is a sign of bad things to come from a tranny!! ps keep the engine oil,and transmission oil changed for long life out of your car engine and tranny. good luck and enjoy your new car......yz-maniac.
You sure its the transmission? Wheezing sound is usually the catylitic converter becoming plugged. Also...at 3-5K rpm you are not idling, you are reving the engine...(in that case, trans may be slipping or flairing between shifts, unless the unit is staying in one gear and just delaying shift till you reach that rpm. actual shift point should be close to 2,000rpm) I'd check the cat first.
change the Speed sensor on the transmition. On my 99 it would not shift out of first gera when my gas light would turn on. Every time it happened untill i filled it up . I changer the speed sensor and all is fine
one unit that operates ratio changes and is connected to the engine is that vacuum operated actuator on the transmission
it is possible that that unit is failing , vacuum hose is leaking and that will cause ratio changes as the vacuum varies
run the fault codes to check for wiring problems or VSS or TCM problems as well
