    Alignment Specs

    Hi there, If the vehicle is street driven, then certainly you can bring the camber up more towards 0. That will help extend the life of the Michelin tires. I do this alot on the 2011 Centennial edition with the SPORT CUP tires as they are very soft and wear quickly. However, I would leave...

    Question: 1984 fuel pump troubleshooting

    Do not put an 85 fuel pump in~~~~~~~~!!!!!! HI there, A 1985 L98 fuel pump puts out 41-47 PSI, which is WAY TOO MUCH for your vehicle. It will overwork the pressure regulator and lead to fuel leakage. This is a safety issue and should NEVER be done! Please be safe!!!! Allthebest, Paul

    HI there, There are a number of factors to consider here. #1, wiring. The six speed manual has much less wiring than a comparible automatic transmission. The 4L60-E, which is what could be installed, requires a different engine control module and the correct wiring to run down the torque...

    Best fluid for '99 T56?

    Hi there, Just to be clear on this, the GM recommendation for fluid lubrication on the T56 has changed since 2006. The correct fluid is 88861800 and is a type of Dexron but it is NOT the Dexron 6. Per engineering guidelines, there is something in the Dexron 6 transmission fluid that is...

    Help! ABS and Traction Control Lights randomly coming on at startup

    HI there, C1243 indicates that the abs motor itself has either stalled or is not able to be moved. I have seen grounds and other issues cause this condition. Normally, if your module is bad, C1255 will set and you will have other issues. It could be as simple as cleaning your ground sources...

    Grand Sport Rough start up on my GS...........

    HI there, No, its not normal. I would be wanting to scan it first thing at start up and monitor the misfire data to determine what cylinder is creating the issue. Its also possible that you have an injector issue based on mileage. But its critical to have the system SCANNED when the problem...

    Transmission Help

    Hi there, Especially if the fluid level is low, these clutches take most of the abuse. The 3/4 clutch is a constant fluid flow clutch, which means if the fluid pressure is lost or compromised, the clutch slips. Also, the clutch can be subject to piston separation and failure which will also...
