Diesel Transmission Repair in Phoenix
Diesel transmission repair covers the automatic behind your diesel: diagnosis, fluid service, valve body and torque converter work, and full rebuilds. Truck & Equipment Specialists handles it in Phoenix, in shop or mobile across the Phoenix metro, with a focus on the Ford 6.7 Power Stroke and its TorqShift transmissions.
A diesel transmission takes a beating in Phoenix. Between summer heat and heavy towing, the automatic behind a 6.7 Power Stroke works harder here than almost anywhere. When it starts shuddering, slipping, or banging into gear, that is not something to wait out.
Owner Jonathan has spent 10+ years on diesels and got known around the Valley for the Ford 6.7 Power Stroke specifically. We know the TorqShift 6R140 that ran from 2011 to 2019 and the 10R140 that came in for 2020 and newer, and we know how they fail. We work in shop or mobile across the Phoenix metro. Call (602) 663-0213 for an estimate.
Diagnose the real problem first
Before we touch anything, we pull codes, check fluid condition, and drive the truck to confirm what you are feeling. A lot of what looks like a failed transmission is a valve body, a solenoid, or a TCM issue, and we would rather find that than sell you a rebuild you do not need.
Fluid and filter service
On the 6R140 and 10R140, clean fluid at the right level is half the battle, especially on trucks that tow in Phoenix heat. We service fluid and filter and check for the contamination that points to bigger problems developing inside.
Valve body and torque converter work
Torque converter shudder and harsh or delayed shifts often trace back to the valve body or the converter itself. We repair valve bodies and torque converters directly, which fixes the shift quality and the shudder without tearing down the whole unit when it is not warranted.
Full transmission rebuilds
When a TorqShift is slipping under load, going into limp-in, or overheating on the highway, it may be time for a rebuild. We do full rebuilds and put the truck back together to hold up to real towing, not just to pass a test drive.
Upgraded coolers and pans for towing
If you tow heavy, heat is what kills these transmissions. For trucks that pull trailers and equipment, we fit upgraded coolers and pans so the fluid stays cooler and the transmission lasts longer in Arizona conditions.
