2005 jeep grand cherokee laredo transmission shifting problems


  • A/T or M/T (auto or stick, gee)
  • if A/T is this the 42RE box>? are you in DRIVE? or 1 or 2 gear.
  • does rpm rise above 3000 rpm > at your attempt? if not ,its a bad engine (weak)
  • is the shift linkage even shifting correctly (movement top and bottom)
  • check levels yet. (and for pink ./red AFT not black-metal flake
  • change the filter yet? or skip service. at 50k miles. ?????
  • check all fuses yet>?
  • using a basic OBD2 scan tool are there any tranny DTC errors?>
  • does the FSM stall test pass? in 1st.? and reverse?
  • if stall fails, slips , then tranny bad. if not its really stuck in 1st gear.
The TCM commads the gear change, there is no valve body brain.
the TCM shifts to second with good inputs to the TCM
if the TCM sees bad inputs it will tell you, SCAN IT.

1987 escort doesnt shift untill 3000 rpm


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.

I just bought a 2001 pontiac grand am se with 99890 miles. I would like to know what rpm is the proper shift point from first to second gear? Mine shifts at like 3000 to 3500 rpm and shifts firmly is that...


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.

WHEN YOU PUT THE CAR IN DRIVE IT WILL NOT GO ANYWHERE


Its the electronic shift control located just under the battery ontop the transmission replace or repair will solve the issue

it'll go into drive but once it reaches 1500 rpm it'll drop into neutral as a safety because at this rpm it is being told to shift gear and when it fails to do so it safely goes into neutral

it will go into reverse just fine and park and you can run all the low drive gears until you reach 1500 rpm then it'll cut it off

i pulled mine out re soldered bad components on the board to fix it but im an electronics engineer it may be easier for you to just replace it

My transmisson makes a weezing sound when im at low speed


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.

Stick shift # Automatic RPM


That is normal,If you do the same speed in 4th gear the rpm's will almost double.

The rpm's will repond faster in a manual than an automatic.

In a manual the engine supplies the power required directly to the gear that you have selected thus the engine rpm's will increase or decrease as needed.

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
