A518 Valve Body

The A518 is on of Chrysler s most popular automatic transmissions. It was introduced around 1990 and produced up to vehicle year model 2003. There are two different versions of the A518; the hydraulically controlled unit referred to as the 46RH and the electronically controlled one referred to as the 46RE. The electronically controlled units have more solenoids in the valve body that the other one.

When conducting a transmission rebuild the valve body should be inspected to make sure all is working well. If the valve body is damaged it should be replaced during the rebuild. This will avoid the extra cost and time of having to replace it later.

If you are simply looking to increase power, harden shifts, correct known issues or totally reprogram the valve body consider one of the many valve body recalibration kits or shift kits available for this unit. Depending on the kit this could be accomplished in a day.

If you do come across a defective, damaged or weak valve body then you need to take the plunge and replace it. Here are some of the different variants:

- None Lock-Up 1990-Up
- Lock-Up 1999-Up
- with Square Connector 1997-1999
- with Rectangular Connector 2000-Up
