Engine races between gears and transmission seems to be slipping. Due for flushing. Only a small wrench warning light on, no code when read. No previous problems like this.

Hello,

I would definitely service the unit, but to me it sounds like the turbine shaft speed sensor is not working correctly. Here is a guide to help with diagrams below:

Both shops we went to for a possible diagnostic scanned the transmission and rode in the vehicle. Quoted approximately $3,500.00 for a rebuild. Thank you Ken for your fast response.
