I have had O2 sensor codes for a while and never messed with them. About a month ago I got a B0035 coffee for left front wheel speed sensor. I replaced the sensor but the light stayed on. It seemed to run fine so I didn't do anything more to it. When driving to work yesterday it felt like my transmission slipped so I immediately pulled over. I had plenty of transmission fluid and had no leaks. When I got it homer today I put the scanner back on it and I now have codes: B0035 (left front wheel speed sensor), B0276 (transmission control module communication performance), B0306 (no DTC definition found), B0327 (no DTC definition found), and my regular O2 sensor codes.... Any ideas on what could be causing all those to show up?

 

Just a guess but being different systems none related. I would star with trans. Get a trans shop to diagnose

 

I guess my main question is what would cause the transmission to not engage in any gear including reverse? I can feel it actually go into gear but still acts like it's in neutral. If I start it up when it's cold it will work like normally for a minute or two then once it warms up it acts like this.

 

I'm going to start at the basics...

* All grounds checked (remove, clean, reattach)
* Both battery connection replaced
* If you have a sun roof have you made certain your drains are open and bcm didn't get wet
* You may want to resolve your original issue and then clear codes and retest
* You've got a issue within the trans control, sensor, electrical etc...
