7 Most Used Transmission Repair Tools

When you’re planning on making some repairs to your car's transmission understanding the various transmission repair tools will make the job go easier. Below you will find a list of seven common transmission repair tools.

Transmission Jack

When you’re working on your transmission by yourself, a transmission jack can be one of the most important tools you can own. This type of jack is specially made to securely lift and lower a transmission. Transmission jacks come in two types: short and tall. The short kind is for use when you don’t have the facilities to raise your car overhead, while the tall one is mostly used in shops with automotive lifts.

Output Shaft Seals

Transmission fluid stains are almost impossible to remove from non-sealed concrete and asphalt surfaces. When performing service work on your transmission where you must removed the driveshaft from the output shaft of the transmission, a properly sized output shaft seal will keep you from spilling transmission fluid all over your driveway or where you have your car parked.

Flywheel Wrench

If you have to disconnect the torque converter or clutch assembly from the flywheel with a manual transmission or the flex plate with an automatic transmission, you’re going to need to be able to turn the assembly to get to the next bolt as well as be able to hold it from turning when removing the bolts and reinstalling the bolts. A flywheel tool or flywheel wrench will be indispensable in this case. Open it up, insert the tooth between two of the teeth on the flywheel or flex plate and you can either loosen or tighten the bolts without the assembly turning on you.

Wrenches

Whether you’re adjusting the clutch on manual transmission, changing the speedometer gear or adjusting the bands on an automatic transmission, you’re going to need a full set of wrenches. If you’re planning on removing one transmission and installing another, you’ll also need a set of wrenches to remove all the nuts, bolts and other pieces that will have to be removed before you can remove the transmission.

Computer Diagnostic Tool

On most newer cars, the automatic transmission is computer controlled. If you own a newer car and are having problems with your transmission, you’re going to need a diagnostic tool, or code scanner, to find out exactly what is wrong with your transmission.

Spline Alignment Tool

If you have a manual transmission that needs a new clutch, you’re going to need something to make sure the splines on the input shaft match up correctly with those in the clutch plate. Otherwise you won’t be able to properly and completely install the transmission once the new parts are installed. A spline alignment tool will allow you to ensure that the splines on the clutch plate align perfectly with the transmission’s input shaft.

Socket Set

If your transmission service or repair job requires you to remove the transmission, you’re going to need a socket set with extensions in order to reach some of the bolts on top of the bell housing.
