SOURCE: automatic transmission is stuck in 2nd gear (limp mode)

most newer vehicles  have transmission control modules,that go to a default of 2nd or 3rd gear when they go bad!  I had a 91 plymouth stuck in 3rd gear because of this module! could be your problem!    when mine went out, it smelled like something electrical burned inside the the passenger cabin! I would check all the electrical connections on the transmission first    good luck

SOURCE: 99 jaguar transmission code p1722

This code is an indication that the transmission has excessive slippage, the code is for the input and output turbine speed sensors, based on what i know of this problem the trans has a mechanical problem, that would be low fluid pressure or worn out forward clutches, make sure the trans fluid is not low, if it is ok you will need to have the trans torn down for inspection..

SOURCE: stuck in 4 wheel drive and wont come out.

hey there i cant tell you what you are missing but i can tell you how to disengage the front wheels . ok you have a vacum line that runs right under the battery and a line that comes up from the front diff. to the same place ( you may have to remove batt and batt tray to get full access to this) un bolt it and temporaly put batt and batt tray back in start it up and decompress this and see if it comes out .... you should here clunking noise if it goes back in ... if thats the case just pull that big vaccum line off .... to test get all four tires off the ground and have some one put it in drive but dont hit the gas it should turn on its own ...if that dont work check the cable that runs down to the differental

My 99 Cadillac sts is in limp mode i believe as it srarts and runs but wont move when i put it in gear. How do i get it out of limp mode?

Sounds like you have a failiing transmission, faulty selector, or possibly a failing Transmission ECU. There are too many possible causes to even guess, but what I can tell you that 'limp mode' will not prevent your vehicle from Driving - It will, however, enable a vehicle with certain failing systems to be driven short distances at limited speeds (with decreased power), but it does not prevent the vehicle from moving - If your vehicle starts but does not move when placed in gear, the problem is not 'limp mode' but lies elsewhere.

Car goes into limp mode wont come out of 2nd

That happened to my '95 OLDS Aurora... Turned out to be 1&2 gear shift solenoid had "popped" out. He replaced new solenoids and a factory patch kit and ****** shifts like brand new. Hope that helps you cause that was less than 10% the cost of a new/rebuilt transmission!

Since you have rebuilt the transmission it is suggested to replace the speed sensor,this is the cause that your car is stuck in limp mode.

try checking all fuses the ones in the fuse box inside as well as under the hood. sometimes you have to check the fuses because of a wire touching in the transmission before you had it rebuilt. Try that out and if not I would go back to whom ever rebuilt the transmission.. I have turning wrenches for 22 years and the last ten in my own shop. I come across allot of 99 silverados with trans and transfer case problems. Hope you find a burnt fuse.
