Transmission Repair FAQ

Can a transmission be repaired on the roadside?

Many problems can be diagnosed and some repaired on site, such as leaks, linkage, shifter air supply, sensors, wiring and clutch adjustment. Internal failures and rebuilds need a shop. The dispatcher will tell you before dispatch if a tow is the better option.

My truck is stuck in gear or won't shift. What should I do?

Stop in a safe place, note any warning lights or fault codes, and call us with your location and the transmission make and model.

How fast can you get to me?

It depends on your location, the time of day and which technicians are available. Before anything is dispatched, we give you a confirmed ETA from the technician who is actually coming.

Is there a warranty?

Warranty terms depend on the part and the job and are written on your invoice.

Do you take fleet cards / company billing?

Yes, fleet cards are accepted. Companies that use us regularly can ask about a fleet account for company billing.
