Good morning,

I need the code number to help you. It should start with a P and then some numbers.

As far as the operation, I would start by changing the fluid and filter. If you have a clogged filter, it will act like this.

Thank you.

The code is for the front brake solenoid circuit. This is located in the ABS module and has nothing to do with your issue.

Did you get the fluid changed yet to see if that is the issue?

Correct. It is part or an indicator of an issue with the ABS.

Oh gosh.
When i put into Drive step on gas it would take a few seconds to kick into gear. Now it does not go at all. A few people. Told us it was transmission, so my son bought one over the weekend. I feel real stupid.

Did you change the fluid? I would try that first before buying a transmission.

Have not done anything only the code reader 3 times. He already bought the transmission. We picked it up in Saturday from Sacramento.

I would change the fluid first. It is about $89.00. A lot cheaper than replacing the transmission.
