Overdrive Conversion

This Triumph Spitfire came originally equipped with a 4 speed manual gear box without overdrive. We're replacing the original gear box with one that is paired with a J-Type overdrive unit.

This style of overdrive uses a cam on the output shaft to drive a pump internal to the unit. When the driver selects overdrive on the shifter knob (only in 3rd or 4th gear) a solenoid allows the pump pressure to apply a servo that engages a planetary gearset which achieves overdrive.

The replacement gear box is 1" longer than the original. Since the driveshaft uses a strap type coupling rather than a traditional splined slip yoke the driveshaft needs to be shortened and rebalanced to fit. A different "platform" and mount also need to be fitted to support the back of the gearbox.

TVR V8S

This 1991 TVR V8S is a rare gem indeed. A 4.0L port-fuel injected Rover V8 engine is used. We had this one in to address various coolant leaks. Due to age some of the hoses had "dry rotted" and the lower plenum to valley gasket plate had compressed to the point that it would no longer seal.

The Importance of Tire Pressure

One of the most overlooked maintenance items on a vehicle is tire pressure. It should be checked regularly and all that is needed is a pressure gauge. As the ambient temperature changes, so can the tire pressure. With classic cars that aren't driven often or have been in storage the tire pressure can be dangerously low. This can cause uneven tread wear or if left for even the shortest drive, internal damage. Below you can see a tire that was driven on while underinflated.

Old vs. Timeless

Although we service many classic cars here, it's not exclusively what we work on.

Many late model vehicle headlights use plastic lenses. Over time the lenses become scratched and hazy. Not only does this reduce the effectiveness of the headlights but the general look of the vehicle appears old and tired.

There are several techniques, restoration kits and buffing compounds available to restore headlights to there original clarity. The key to making a clear finish last is to wax the headlights on a regular basis.

Below you can see the transformation of a Mini we had in.
