Lambda/Oxygen Sensors Reduce Emissions

An oxygen sensor allows your engine to run as smoothly as possible, because it measures the exhaust gases and relays information to the fuel system control unit. With this information, the control unit can fine-tune the fuel mixture for optimum fuel economy and power. A dead oxygen sensor can also lead to significant idle and performance problems.

Throttle Body Cleaning Kit

We get a lot of calls about Volvos (1982 and later) that will not idle consistently, idle too high, or may be hard to start. As with most running problems, the first suspect is not always the culprit. In other words, the idle motor may not actually be the problem, and replacing it may not always correct the idle. Often, the cause is a sticky throttle body that simply needs cleaning. This kit outlines the step-by-step procedure for removal, cleaning and resetting of the throttle body on 1982 and newer LH jetronic cars. It includes the throttle plate gasket, cleaning brush, cleaner solution and complete photo instructions. For use on all 1986-95 4-cylinder gas models and 1982-85 models with LH electronic fuel injection.

Automatic Transmission Overdrive Fix it Kit

If the overdrive has stopped functioning in your 1983-1995 240, 740 or 760 with automatic transmission we now have an economical fix for the most common failures. The most common failures are the relay, the solenoid and wiring which can run well over a hundred dollars to trouble shoot and repair. Our new Solenoid block off kit, bypasses the entire system and allows the trans to shift in and out of overdrive automatically. How many times have you used the OD button on the shift lever to shift down for hills or while towing? It’s really not necessary for most drivers.

Automatic Transmission Tailshaft Bushing Repair

Kit A worn tailshaft bushing is a common failure in Volvo automatic transmissions that leads to fluid leaks and eventual clunking under load. Replacing the seal may stop the leak for a few weeks, but if any discernable play can be felt in the tailshaft, the bushing must be replaced to prevent future leaks and more serious damage to the transmission. It’s necessary to remove the entire tailshaft housing to press out the bushing and press in a replacement. We have a kit available that includes the bushing, seal and housing gasket.
