After my wife ran to the coffee shop in my car she advised she had spilled coffee all over the shifter. Its a good thing she's cute .
it ran fine before . I have pulled the trans computer an replaced with a used exact number replacement as the original was soaked with trans fluid .
replaced the connector at transmission it was leaking badly .
I took apart the shifter cleaned it out no apparent issues nor much junk or anything out of the ordinary .
It will not start in 1st . in fact struggles to get going like it in 2nd gear from the start ,
It will not manually down shift in any gear .
It will shift up unitl 4th .
are these signs of being in limp mode ? if so our there any for code readers that can remove the error as I have noticed a lot do not work in a 1996.
The car has 150,000 miles .
Any help is greatly appreciated .
