Transmissions & Differentials

Transmission and differential repairs and maintenance — keeping the drive train dependable rather than waiting to replace it.

What to expect

Drive train work is where regular service pays for itself most obviously. A differential that gets its fluid changed on schedule and gets looked at when it starts to whine is a repair; the same differential left until it lets go on the freeway is a tow, a rebuild, and a week of lost revenue.

Our emphasis here is repairs and maintenance — keeping what you have dependable — rather than defaulting to replacement. We work on manual and automatic heavy-duty transmissions and on drive axles and differentials.

Straight Answers

Transmissions & Differentials — common questions

My differential is whining. How urgent is that?

Urgent enough to get looked at now rather than next month. A whine is usually bearing or gear wear, and caught early it is often a bearing and a seal. Left alone it takes the gears with it and becomes a far larger bill.

Do you rebuild transmissions or only replace them?

We work on them. The point of this service is keeping your drive train dependable, so repair and maintenance come first — replacement is the answer when the numbers say so, not the default.

How often should differential and transmission fluid be changed?

It varies by unit, by duty cycle and by what the manufacturer specifies — a truck pulling heavy in the hills is on a shorter interval than one running flat highway miles. Tell us how the truck works and we will set the schedule against the manufacturer's spec.

Where We Work

Transmissions & Differentials across East County and San Diego County

The shop is on Riverside Drive in Lakeside, so the tow is short from most of East County — and a short tow is real money on a truck that will not roll. We take work from across San Diego County.
