D4 light on is blinking/Code 1773
 

my d4 light is blinking and the check engine is on also, when i checked it with the scanner i got a code 1773 for Automatic transmission malfunction great another problem

probably p1730 code or a p1750

incorrect gear ratio.
clutch pressure failure.


check lfuid, check for leaks, if not it's an internal trans. failure and you will need a trans.

This is certainly nothing out of the ordinary for a TL.

already check the code 1773 and its the clutch pressure plate control selonoid valve B which only cost $37 and its on the ouside of the tranny so its not a big deal

The diagnostic proceedure for that code is 11 steps long and could lead to anything from a bad solenoid, to a wiring harness problem, to a bad PCM.

You could go the "cheap" route and put in the new solenoid - since you know all about it. Just be warned that a new solenoid may not fix that code.

thanks man i already got it taken care of, it was one of the electrical connecton on the tranny that was loose so plug back it in and reset the check engine light

Glad you got it covered! :thumbsup:

Nice! you didnt need a new tranny.:thumbsup:
