If the check engine light is on instead of won't to check the transmission fluid , have it checked for DTC'S - diagnostic trouble codes . More then likely TCC clutch solenoid problem . Take it an have it check .

In most vehicle, Transmission warning light incorporated in Check Engine light (ie, when you pull check engine light codes, transmission trouble code will be among it, if there were any), other case, its in your PRNDL indicator light (ie. PRNDL light will blink when transmission has problem), and in another case, you need to have a special scaner that capable of pulling transmission trouble code. I hope it helps :)

Probable transmission problem check fluid level look for debris in fluid scan check engine light if it's related to the transmission scan transmission side

yea it does if there is a transmission code it will appear. i naver seen a light come one in a manual transmission except bmw. auto trans will give you a light

P0700 is a code that tells u the TCM [transmission Control Module] has requested that the PCM [Powertrain Control Module] turn on the check engine light, u now need to ge the TCM tested for the transmission fault code(s) that were stored when the check engine light was turned on by the TCM through and by the PCM

Your computer pick up a bad reading from one of your engine or transmission sensors, you'll need to have computer diag. done to find out what sensor is the problem.

low transmission will not turn on the light, only a coincidence, you need to have the code read with a scan tool to fix the problem and turn off the light.

The transmission is in limp in mode. The check engine light is on because the transmission controller told the engine controller to turn it on. You will have to get the fault codes checked to diagnose the problem. Expect to find a P0700 code in the engine controller. Thats the code for a transmission fault in the trans controller. It could be as simple as an input speed sensor or as complexed as an internal failure. Either way have the transmission fault codes checked for a proper diagnosis.

You will need to get the diagnostics done for the check engine light and get a transmission flush for yoru car.
