How To Tighten Torque Converter Bolts

Typical torque converters feature three to six bolts holding the converters to the flex plate. How can you tighten these bolts when they become loose? Use our simple guide below.

How To Tighten Torque Converter Bolts Properly

To properly tighten your torque converter bolts, it’s recommended to use a socket wrench and torque wrench for the task. Follow these steps:

Start by locating the torque converter bolts.
There are typically four bolts located on the outside of the transmission.
Use a ratchet to loosen each and every bolt at least a few turns.
After all the bolts are loose, tighten them back up with your ratchet.
Tighten all the bolts evenly so they are all the same tightness at this time.
Double check that all the bolts are tight enough by wiggling them with your fingers.
Retighten them until they are snug, if they come loose.

How Tight Should Torque Converters Be?

The answer to how tight a torque converter needs to be is not so simple. It all depends on the make and model of your car, as well as the manufactured year. There is no one-size-fits-all answer since there are so many different sizes and types of torque converters. It’s recommended to consult your vehicle’s service manual to find the best answer.

If you do not own a service manual, it’s possible to find this information online or call a local dealership or auto parts store. Always make sure you know how tight these converters need to be before making this a DIY task. Over and under-tightening can lead to serious issues down the road.

What Do Loose Torque Converter Bolts Sound Like?

If your car features some loose torque converter bolts, it will most likely cause a rattling noise. This happens when bolts become loose and eventually fall out of place. Whenever you notice this noise, it’s important to have the car examined by a professional as soon as possible.
