TC015-06 TCM CALIBRATION UPDATE: M.I.L. ON DTC P2716 (REVISED) 2007 model year Camry vehicles equipped with the 2GR–FE engine and 6–speed automatic transmission, produced BEFORE the Production Change Effective VINs shown

Under certain driving conditions, some vehicles may exhibit a M.I.L. “ON” condition with DTC P2716 (Pressure Control Solenoid “D” Electrical [Shift Solenoid SLT]) and no noticeable change in vehicle operation. The Transmission Control Module (TCM) calibration has been revised to address this issue.

NOTE:
Version 14.0a or later Diagnostic Tester software is required to perform this procedure.
Before proceeding, verify the TCM calibration has NOT been updated by checking for the Authorized Modifications Label (shown in step 1 of the Repair Procedure).

Production Change info added:

JTNBK46K#73018063
4T1BK46K#7U028561
4T1BK46K#7U535098

I've seen action on this DTC previously... This is a revision to TSB not related to the shift flare in the TSB instead it deals with a MIL = Malfunction Indicator Lamp. Posibbly not even noted as an issue by the driver until the light goes on.

A MIL is not displayed when the transmission flares.

HOWEVER...

It's interesting to read the sequence of repair steps... These are in sequence of steps, it the MIL still activates, you go to the next step.

1.a. CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P2757) ---->>> GO TO DTC CHART LOOK UP CODE

1.b. INSPECT SHIFT SOLENOID VALVE SLU ---->>>

2.a. If No Good: REPLACE SHIFT SOLENOID VALVE SLU

2.b. If OK: INSPECT TRANSMISSION VALVE BODY ASSEMBLY ---->>>

3.a. If No Good: REPLACE TRANSMISSION VALVE BODY ASSEMBLY

3.b. If Ok: INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY ---->>>

4.a. If No Good: REPLACE TORQUE CONVERTER CLUTCH ASSEMBLY

5.a. If OK:REPLACE AUTOMATIC TRANSMISSION ASSEMBLY

My car comes under this TSB, but I've never noticed this problem.

clarification

for those of us who are not mechanics, would someone mind explaining in layman's terms what this means?

"...may exhibit a M.I.L. “ON” condition with DTC P2716..."

MIL = Malfunction Indicator Lamp <<<---- e.g. idiot light or some call it the "check engine light"

DTC = Diagnostic Code

Basically what happens is the idiot light goes on and the TCM in this case stores a malfunction code... As referenced in the actual DTC, for some reason I ran into the next one 2757 in my previous post.

"When an open or short in the linear solenoid valve (SLT) circuit is detected, the TCM interprets this as a fault. The TCM will turn on the MIL and store the DTC."

Basically what you need to do is get the U660E factory service manual and lookup DTC P2716, I just do a ctrl + F and then type in 2716 before I hit enter.
