My 97 chrysler town n country has hard downshifts n gets stuck in second gear after its driven for a while once i turn it off it works fine for a few minutes then problem begins again. for the first 45...


It is going into "limp" also called "limp-in" mode. It is a default mode the computer places the transmission goes into when it detects certain errors. In this mode you should also have a Service Engine Soon (or Check Engine) light illuminated on the instrument panel. This light tells you that the computer has logged an error code(s). Autozone will attach a code reader and pull the codes for you at no charge. Have this done and post the codes back here for further assistance.

1997 Chrysler Town and Country Transmission clunks with downshift


Check the universal joints in the drive shaft to rear axel. 120,000 miles, its time for replacement. Safety hazard exist, check soon. Also transmission filter should have been serviced at 60,000 miles. Its time.

This is called the limp mode. It means that you have a transmission problem. It goes into limp mode to protect the transmission from total failure. You need to take it to a transmission shop to perform a diagnosic test to see if it needs repair or replace

Trans wont shift up or down..gearbox fault light on


Hello jjames696...The gearbox fault light has come on because the transmission control module (TCM) has received a fault signal from one or both of the two trans. sensors....The Output Shaft Speed (OSS) Sensor and/or Turbine Shaft Speed (TSS) Sensor.The TCM has now defaulted to limp mode...A diagnostic scan needs to be run...An OBD II scanner will retrive a P1722 fault code, the only code in it's library for the ZF5HP24 transmission. The WDS / IDS will pull other codes not found in the standard OBDII library (dealer or good transmission shop)
When was the last time the transmission was serviced? Manual shifting will take it's toll on the fluid quickly.
The transmission is sealed, no dipstick (which i think is a bad idea) You can check the fluid level by removing a plug on the passenger side of the case, you should be able to touch the fluid with your finger. Jaguar fluid is VERY expensive, Mobil 1 synthetic will work and meets ESSO specs.
Personally...i would change fluid every 25-30k.
Hopefully all you have is a bad sensor or a stuck solenoid and no internal componet damage.
Good luck, hope this answers your question...please take time to rate my fixya reply.

2001 chysler T&C downshifting


It must be seeing a fault coming out of 4th gear. The downshift is "Limp In" mode. That is about when the Clutch Volumn is recalculated. It may be having OverDrive issues (which is internal) You need to have a diagnostic done with a scanner. Find out which fault is occuring and then go from there. There may even be updates for the TCM. Let me know how that goes?

1991 bmw 520i transmission goes into 'safe' mode


quoted from BMWE34.network
" Transmission locks in "limp" mode - 3rd gear so you can "limp" home or to your nearest dealer."

"Things to check before even contemplating a transmission overhaul:
Check electrics - Alternator and battery.
Replace DME Relay and Fuel Pump Relay - not expensive.
Remove disassemble, clean and reassemble gear selector switch - If it looks beyond saving, replace ($200)
Service the transmission ($130 from a specialist) and check/replace transmission speed sensor ($90)"

2007 Lincoln MKZ Transmission goes CLUNK on low speed downshift


sounds like an electronic fault caused by the mini computer controling the gearbox functions,try another dealer as dealer only as good as the mechanics it employs.and like the old adage if you only pay peanuts you only get monkeys.but thinking about it ,their is a possibility of a piston sticking in the box thats controling the brake bands.buy a manual next time
