Newer Low Mile Tranny Slips in D only

[malayan]

I have a 90 Camry DX that we replaced the tranny with a LOW MILE tranny from Japan Engines Inc.
I have got 4-5 of these tranny's with no problems ever. They usually have 30-40k and are very clean in and out

This time I did the R &R with no problems.

My customer drove it for one day... then it would slip in D only from a dead stop.
She dropped it too D2 no change Drop toD1 and it would take off.

I called the Jap Inc. they seem to think it could be the shift down cable adjustment or ...... are they just stalling?

Thanks in advance

did you check the fluid level with the car idling at operating temperature.......?

sounds like your just missing fluid.

[malayan]

Fliud is good. ... I had to troubleshoot myself and the car was starting out in a higher gea.. D2 no change then D1 took off fine

Gonna be adjusting the timng and kickdown cable. Then100 miles to break this tranny in a bit more....

you would be surprised the stories I have read. And I never said you were stupid. But you did not mention you did any diagnosing other than sitting in the drivers seat. It helps a lot more for us to give you answers when you post what you have already tried and found to be good or not good for the future.

your torque converter is missing fluid. I bet it was removed, fluid escaped and no one refilled it so the clutches are slipping. Or your trans filter needs to be changed its not allowing enough fluid to pass. Could also mean there is more miles on your tranny than you think.

kick down cable does just that, downshift. But you have to be asking the transmission to down shift by pushing on the throttle. If you let off the gas and slow down the transmission automatically drops down its gears. So they are just bullshitting you the kick down cable has nothing to do with the transmission physically slipping.

just some ideas.

Thanks for the info . You sound like someone who works on tranny's. Do you know that the tranny gets filled at startup and then can drain up to half when shutoff? Thats wh you need to check tranny fluid wwhile car is running.

* So unless I have a pump issue ..It is not the converter fluid being low!

adjusting the kickdown cable

I'm well aware of the Japanese import shops and their politics I frequent the shops in my area often, I even bought a car there. For the most part what they say is true, but nothing stops them from selling you high mileage parts because how will you know? Japan has no winter so the cars in general stay really clean. You go from swapping lets say your transmission which is filthy as all hell for one thats all clean and you think "low mileage" not necessarily true.

The pump WILL fill the converter but marginally to say the least, you would be surprised how much fluid you can fit into a torque converter and it usually takes 15 minutes of pouring and waiting to fill it. If it was left to spill it leaks very slowly so no one may have even noticed it lost a large amount of fluid. If the converter isn't "primed" properly by fill it up to its max it could do exactly what you are describing and not have enough fluid to displace internally to create the vaccum necessary to draw in more fluid from the transmission, in turn slipping. The fact that it is a couple days later is just hit or miss, it may have been on the brink of missing fluid and perhaps a small amount got sucked back into the transmission and now is causing this condition.

While the converter is spinning it flings its oil to the outer edges making a "vacuum" type action to suck in more fluid, but if its missing fluid you can imagine why it wouldn't be able to make enough vacuum force to draw in more fluid.

Ask them if they are willing to take it off the car for you and verify that they had not made a mistake not checking the fluid level because there is no way you can do this with the transmission on the car.

DOCTOR J PM me this message:

In first gear both at D and 2nd ranges the tranny uses the same holding devices; ; I've seen the similar problem (slips in D but takes off in LOW, and it have been caused by broken F1 one way clutch).
How is this problem happening: you shifted to D, car does not move; you give it gas the engine goes to 2000 rpm and car barely moves
or
the car starts to move goes to 15 mph but does not go to the second gear instead it runs at 20 mph @3000 rpm?

THIS SEEMED TO BE THE CASE LIKE STARTING IN A HIGHER GEAR THAN 1st. But after adjusting the kickdown cable. Maybe that was it

[mk2-1jz]

He is the expert lol But that is much harder to diagnose!

[malayan]

Yes! Hard to diagnos until you get it apart and see the clutches. I got the car back and the fluid was 1 qt overfull. I drained to proper level at Idle and Temp. Drove around the block and then for a few miles and nothing unusual.


Had to adjust the kickdown and now seems fine [/SIZE][/B]

Gonna let my buddy drive it for a day or two and see. its OK



Had to adjust the kickdown and we will see

[mk2-1jz]

If it was overfulled it would just build excess pressure and either open up the breather valve and leak out or it would come out the oil dipstick when it got hot enough.

Dont know if that would be what caused your slipping, but it is definitely not a good problem to have. But excess pressure might be a cause of abnormal shift conditions. We'll see what Doctor J says as well.

[malayan]

Had to adjust the kickdown cable and now seemed fine..

.THEN IT DID IT AGAIN THIS MORNING AFTER 15 Miles..STRTED OFF IN 3rd and stayed there till 55

Talked to the tranny guys here and they are so busy it's not funny and theyWanted me to drop it off for a few days.....NOT!

thought it might be a GOVONOR

I gotta PM The DoctorJ .

A140E automatic transmission

I been talking to Doctor J and found that after I troubleshoot this problem we have decided it is most likely the solenoids not get sigal or not responding to a signal.

The tranny probably sat in a warehouse for a few years and when the solenoids don't get ECM signal (bad ecm or connection) they most likely will cause to start in a higher gear from a stop ...RANDOMLY ...Maybe once in 2-3 days.
Before pulling or checking the solenoiids I decide to run 1000 miles and see if it works itself out.

If it starts to do it every start up then I will post and update and a hopefully a confirmed fix.
