Semi trucks are big and heavy, which means that it takes a lot of energy to get them moving. Hauling heavy loads for thousands upon thousands of miles means that transmission repair is an inevitability for most truckers. In this article, weâll walk through some common signs that your semi truck transmission needs attention, explain why itâs important to get repairs done by professionals, and give you an overview of how the process works so you know what to expect when you bring your semi truck in for repairs.

What Happens If My Transmission Fails?
The cost of this repair ranges from $5,000 to $15,000 for semi truck transmissions, so it’s not something you want to take a chance on. If you’re out driving and your transmission fails without warning, it’s best not to keep driving or try going down the road at slower speeds as this could cause more damage and costly repairs. Instead, pull over as soon as possible and contact your nearest qualified truck transmission repair center or tow service for immediate help. The goal is to get the vehicle out of traffic ASAP. It may also be prudent to warn other drivers of the danger in the vicinity by putting on hazard lights and positioning safety cones nearby.
Preventative Maintenance For Semi Truck Transmissions

What Are the Signs That I Need to Get My Transmissions Repaired?
Worn transmission components can cause problems like the inability to shift gears, excessive engine rpm, and an increased braking effort. There are a number of signs that may indicate your semi truck’s transmission needs repair or replacement. The most common symptom is failure to shift gears properly. If you notice your clutch shuddering as you change gears, that could be an indication that the clutch is about worn out and needs replacement. Other symptoms include hard shifting, no power when accelerating from a stop, or a high engine speed when idling at a stop sign. These could all be signs of trouble with the semi truck’s transmission and should be repaired as soon as possible before more damage occurs!
