Hello all,
94 Camry with a 4 Cyl. A140E Automatic trans. 175000 miles.
Transmission will not shift properly. I thought it was running in fail safe. It immediately shifts to 3rd. It won't hardly pull itself starting out unless I manually put it in 1st, then shift it to 2nd, then to drive.
Fluid is not burnt & it does not slip. It just won't shift normally.
Code 63 on the Trans. O/D light flashed a 6 3. According to the manual that is a malfunction with the #2 shift solenoid. After clearing the code it has not come back.
I have run all the diagnostic test & everything checks out. Sensors, solenoids, voltage from the ECM and the wiring all check out ok.
I took the pan down & removed the solenoids. They checked out ok electrically. Opened & closed ok when energized & ohmed out Ok. Put them back in & still no good.
I am confident the trans is not fried because it does not slip when shifted manually, the fluid was not burnt, & there was no debris in the pan. When I disconnect the connector from the shift solenoid and do the manual shift test as described in the manual it does ok.
I went ahead with hesitation & replaced the shift solenoids, because I was told by several auto techs that sometimes they just will not work in the vehicle, even if they bench test ok. Still no good.
I made up a switch box with 2 switches & connected it directly to the shift solenoids. This completely separated the trans from the computer inputs. It still would not shift properly when I energized the shift solenoids according to the matrix I found in the diagnostic manual.
So now I am going to pull the Valve body. I was told by a Trans tech that sometimes the check balls between the valve body & the separator plate can deteriorate & and block a passage.
Does anybody have any other Ideas or input?
Also I am looking for a diagram or drawing that shows how many & where the check balls should be. Can any body help with where I can find this info?
Thanks & I’ll post when I succeed with this problem!
BTW the Camry manuals that are posted are a great resource!
