If the EPC pressure is not within spec you can move onto a pinpoint test. The steps are as the same as above with the exception of you connect the gauge to the EPC pressure tap instead. If the pressure is not within specification you’ll need to check the EPC pressure.

This is only necessary for the 4R7xx series of transmissions. Testing your transmission pressure will help identify what component of your transmission is actually failing.

(Related Article: How to Check Your Transmission Fluid - ) Step 3 – Test Transmission Pressure If the fluid is foamy and thick, then there's engine coolant or water in your transmission fluid. If the fluid is brown or smells burnt, it needs to be changed. Likewise if it’s overfilled, drain some out. You’ll need to check it while the truck is running and the transmission is warm, usually a 1 - 2 mile drive is enough to warm it. Hard shifts, Transmission Warning Message. The line pressure control solenoid is shorting out. You may be stuck in gear and have strange shifting from one gear to another. Slipping shifts, harsh shifts, no shifts, Triggers "Limp home mode," Transmission Warning light, and maybe Check Engine Light. Engine flare in missed gear, hard shifts, TCIL May cause Check Engine Light, will trigger Transmission Warning Light, inability to shift from 3rd, hard shifts, "slipping" transmission/No TCC engagementĬheck Engine Light, hard shifts, "slipping" transmission/No TCC engagement Short circuit, noisy or lost signal, no signal

Transmission is slipping, TCC operating erratically Limited torque, slipping transmission, or harsh shifting if the circuit is stuck open. TCC is slipping excessively due to internal, mechanical issues. Engine might stall in D at low speeds or never engage. TCC solenoid is failing or TCC is slipping excessively. Solenoid is either stuck closed or open due to a physical failure.
