Check the speed sensor installation. |
|
|
Inspect the speed sensor O-ring for wear and damage. |
|
|

Improper alignment of the ATF pump and the torque converter housing may cause ATF pump seizure. The symptoms are mostly an rpm-related ticking noise or a high pitched squeak. |
|
|
Check the main regulator valve in the regulator valve body for free movement, and check the valve springs for wear and damage. |
|
|
Check for a clogged orifice in the separator plate. If the orifice is clogged, remove it and clean the separator plate orifice. |
|
|
Check the 1st accumulator piston, the O-ring, and the spring in the manual valve body for wear and damage. |
|
