Dear Kashif,

I have not scanned again since I came back to Lagos. The sluggishness is evident after shifting to gear 3 while about to climb the hills. The sluggishness did not stop till I got to Lagos but the hills from Ore to Lagos are not as high as asaba -Benin road. When the gear is cold, it jerks when I shift to reverse position.

Kashif:


Like you have been advised, get external cooler.

xvbill:
Man i like your pasion

Kashif:
Valve body washed and cleaned. The next step would be to check all ports for leakages. If any is out of spec, it will be repaired. My chinko vacuum pump died on me without doing much . Need to get another soon - praying for time....

I will post test results when ready; enjoy!

Kashif:
I did mention that I increased the pressure in the transmission due to the fear of a possibly worn clutch. Saturday, I decided to return it to spec (I was hearing little engagement clunks).

On opening the drain plug, I was pleasantly surprised that the ATF was as pink as it was when I worked on this transmission. Could it be the elevated pressure holding the clutches and brakes tight, with minimal wear? Good to know!

On a side note, after dropping and adjusting the valve body, I coupled everything back, refilled fluid, reset adapts and it was time to test. Engaged reverse, there was no movement. Neutral, and there was a jerk, and there was forward movement! Drive - forward movement. Engaged reverse again, and there was forward movement! So, I had forward in all ranges! LOL! . So it clicked! I did not connect the manual valve. Very funny but a fundamental oversight. Wacked myself on the head!

Had to drain fluid, drop pan and VB again, just to connect the manual valve. After that punishment, everything was fine again. Thank God I kept that day to myself!

onwards:


Salute!
Want to be like you when I grow up... Really.
Good thing about DIY is the confidence it instills into you when you finally get it right.

Took one year plus and you still stuck at it.
Salute once again!

Mr. Kashif, well done boss! I stumbled on this thread whilst searching on net for a forum that has useful info relating to gear issues, what more? This thread you created is undoubtedly the best! To think that you ain't really a mechanic but dedicated so much time to finding a solution to what transpired on your transmission, mehn, I'm perplexed! Your own engineer na talent/gift.. Lemme briefly narrate my ordeal.

So "recession" is here and a young man decided he should use his life savings so far to get a vehicle and make ends meet from transportation... I opted for a Sienna, tokunbo is quite on the high side, way above what I had, so Nigerian used was the alternative... So I saw this 2005 AWD Toyota Sienna on OLX, went along with a mechanic recommended by a friend to check the vehicle out, he drove it, said engine and transmission were good! "Minor services such as working on the suspension, changing steering oil pump and gearbox oil pump/seal", so I got the car.. Whilst driving down home, got into a pot hole with both legs on speed, 5 mins later, front legs sized whilst on speed (thank God it didn't result to an accident), tried moving the car and it kept on this struggling to move thing with a severe grinding sound, had to park and had it towed down the next day to his workshop. On getting there, started the car and discovered the seizure was not longer there and the car was moving normal front and back, told him it seems this ish was gone, he insisted it's a problem with "axle differential" and had to be worked on else it would repeat again.. Lemme cut this story, after spending so much for the fix of the axle differential, change of gearbox oil pump and the suspensions, now I went back to check on the progress, went for a test drive, it was a whole new problem When car was driven for like 10mins, it stops to move, would remain static, I kept firing and no way! Turned off engine, returned gear selection to neutral and pushed the car outta the road, turned on engine again and selected reverse, it moved, sent back to drive and it moved, back to the workshop, he called someone who's supposedly a gearbox specialist, and he recommended a filter should around the gear really don't know what that meant, should be changed or cleaned properly.. I came back the next day he said he had done that.. I went for a test drive again, now car doesn't stop moving on it's own, but I noticed too many abnormalities....

When I turn on the car and select reverse, it doesn't move, once I take it to drive and move forward a bit and then return it to reverse then it moves, the reverse can't/struggles to climb a hill, each time I transmit it, it makes this "giggi" strong sound, doesn't pick up fine from start but pick later and comes with a really rattling noise!

Help!!!! I'm feeling the transmission is ruined!

The mech guy said the gear is 10pin, that it comes with 13pin but it seems the previous owner prolly changed it to the 10pin..

Please I need your professional advise /suggestion, I reside in Port Harcourt... I'm afraid of taking it back to the mechanic guy as I feel they would destroy more things in course of repairs cos this ish started after the supposedly axle differential repairs..

Kashif:


Wow! What an ordeal! I empathise with you, but with all I have read above, that your transmission could be toast. Why on earth would they change the pump?? Anyway, that was a lie, because it is impossible without dropping the transmission. How is the fluid now? Burnt? You may have been better off not listening to your mechanic when he suggested service.

I am afraid you will need to replace it with the correct transmission - U151(13pin). That may be the real reason for selling the vehicle.

They did dropped the gear, I was present when the supposed specialist came to pick it up to go change oil pump/seal, same time the axle differential guy came to pick the axle differential for repairs as well.. I wanted he let the gear guy fix it right there at his shop, but the gear guy said he has to take it to his own shop as the tools he require for the fix and all are over there.. I outrightly told my mechanic what if this tranny comes back not healthy? He said the gear guy would pay should he damage it....

Now who go pay na? Nobody.. .I'm just in a mess right now.. Prior to the cleaning of the filter or so that after which the car could now move and not stop moving upon accelerating after 10mins drive (when car heats up), he tried to check the ATF gauge when I arrived from the test drive, it was like a frying/severe burning was going on in there, smoke kept evolving from the opening where the ATF fluid is poured into, but that stopped after the cleaning of the filter, he said it was blocked with much debris and prevented air from going in blah blah.... Currently, this transmission is just not performing well....

The 13pin, how much would it cost to have it on this car? Thanks boss!

cardoctor:
@Kashif

You are still not done with this gearbox?

Kashif:


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.

Inception:


Bro, pls how much is the U250E transmission?

Pablo212:
I paid 270k for a U151E, they ripped it from one 2GF engine (07 Avalon) took it from Ladipo to Bode thomas, the mechanic guy that was recommended by the seller mounted it in 2 days, 3rd day he started it, after doing some wiring stuffs and changing the brainbox he ran the car for abt 15 mins till it gets hot and stopped engaging. cut long story short we returned it... now we got another one after adding 70k to the outstanding 270k because the seller couldn't bear the loss alone, we agreed on taking another gear, now its in the mech's workshop. I hope this one works because the seller assured the only problem with this one we are taking now is the pump, all we need to do is replace the bad pump, take it out of the first one and put it in this one that needs pump replacement.


I just hope it works out tomorrow, otherwise, am still in the market for a U151E tranny.

Mogbe!!!!

King Gazzuzz, Emir Kashif et al abeg come help oooo

Kashif:


Shaft replacements have been carried out after the vehicle was left over night, and still had problems. I really dont think the temperature is the culprit.

ZF for instance, even asks you to ensure the vehicle is at operating temperature before changing atf.
