This is the third time "changed pump and transmission died" is being reported. I don't know how they do it for this to occur. The only thing that comes to my mind is dirty work environment. I once worked on a Toyota Sienna, and from the way my guys handled the transmission on installation, I told them that the transmission will not work. Even if it worked, it would be for a day or so. And it did come right back! Valve body was full of sand!

With the filter cleaning, am sure he meant ATF, and not air!

With the overheating and smoke coming out of the dip, that transmission cannot be used in its current state. The clutches and brakes must have burnt up.

Possible solutions:

Replace current transmission with original U151(13pin). The current price is prohibitive (430k)
Replace current transmission with a U140 (10pin). About 240k with the rear differential.
Repair the current transmission - valve body must be thoroughly cleaned, burnt cluthes/brakes/steels replaced.


Best of luck.

There is something you guys are all overlooking. ALL the codes are electrical. It makes a lot of difference.

If he has performance/ratio code(s), then I will agree the fluid could be a culprit. The computer knows the difference between these two. The ammeter in the computer is constantly measuring the electrical behaviour of the actuators and sensors. It knows the range of feedback expected. In electrical codes, its either the computer's signal is not reaching its destination, or the feedback is not reaching the computer (in the expected form/range). Electrical codes will trigger ratio and pressure codes, but I don't see how it could be the other way round.

Temperature sensors are thermistors so they cannot tell if they are sensing palm kernel oil or vaseline. I don't see a bad fluid taking it out.

Yes, all very well. Seems the OP is so engrossed with issue to pay any attention here (for the moment). Anyway, since I'm presuming the car in question has a VQ35 engine, I'll still settle for the step motor. The part is so sensitive that it could be damaged by an electrical glitch, improper battery connection for instance. The damage might not even be immediately noticeable if minor impairment had resulted, thus making it difficult to associate the damage to the glitch. At all events, it sure would be less expensive if it was a step motor issue. If the temp sensor was damaged, then another valve body is required, which in our local context means transmission replacement.

Seen. I'll get back to you after some consultations but, we'll need to take a very good look at your prices and review accordingly. I hope there is room for negotiation?
