Outstanding integrity and customer service! Took in my ancient Previa (1995, 325K miles) because I felt a new vibration, suspected tranny. They quickly checked it out: test drove it, checked fluids, put it on the rack, etc and decided I had a brake issue but the vibration was a mount or isolator ... which they don't do on my car because they would be inefficient since they don't work a lot on Previas. So, they declined to charge me anything for the diagnostic!
BTW, a few years ago we had these folks put a tranny cooler on our horse-towing pickup, and it's been doing fine.
