AB60 Upgraded Modified Valve Body- Toyota AB60F and AB60E *If you cannot find a shift kit for your Tundra, LX570 AB60F or AB60E click here!*

We are able to modify your existing valve body for high performance operation. These are the same modifications that are included in our line of performance transmissions.

In addition to the valve body modifications that yield quick, clean and positive shiting that improve durability and overall transmission performance, IPT also repairs worn valve body components, such as pressure regulator components and lock up control and relay valves, which can cause or contribute to code P2757- torque converter slip, torque converter shudder and other lock up related malfunctions.

In a properly functioning transmission, the modification fixes, prevents, or reduces the incidence of codes P2714, P2757, P0740, P0741, etc- soft, flared or delayed shifts and torque converter clutch slip, shudder, torque converter malfunctions and torque converter clutch circuit or stuck off codes.

These codes are almost never actually caused by the solenoids themselves.

Now includes pressure regulator valve rebore and installation of Sonnax 147741-04K (oversize pressure regulator and CNC machined pressure regulator and boost valve sleeve)

*Please note: This is a modification service, you must send your component to IPT to be reworked. Normal turnaround time is 2-3 days at our shop.

For an exchange modified valve body to receive core deposit refund we must receive a properly functioning valve body in good condition. Also note, core exchange valve bodies for AB60 are shipped without solenoids, you must change over your existing ones to the valve body that you receive from us.
