I have used Kens Transmissions on E Bell Rd in Phoenix. He has been servicing our auto transmissions for 5 years. My friend recommended him after sending all 140 of his fleet vans there for years. They have been in business 26 years at the same location.
At 60K miles I was talked into power flushing the trans in my wifes Expedition at a Ford dealer. Recently Ken told me never to do this. At 75K he was rebuilding that trans for us. He reccomends chaning the fluid & filter every 30k miles instead. Every other Saturday he has drive up appoinments for about $50 depoending on vehicle.
