Re: Rebuilt tranny, fail when hot, any idea??

Hi, how are you, sorry for don update the post, it was because i was slighly busy, but well, now i am a little more "free"

well, lets continue with the history. finally at the last chance before droping out the tranny again, i replaces a rebuild valve body, the result: the same, no reverse, no first, all the other was just right. so what was the problem, well, the inside.

but well, i needed the van and i just take it to travel to a relatively far distance (aprox 100 miles) and during all the travel the van do it very well (except for the problem of course) but when we were returning, form a moment to another, it started to drop the oil, and lot of smoke comes from down the van.

i inmediately stopped the van, and well, the oil was falling out from the space that is between the engine and the tranny, so, the failre could be a damaged converter seal, o a bad torqued bolt from that side of the trany.

so finally the van supported all the highway travel, but in the city it was no more oil for applying the clutches, and it was towed to home.

to the day of today, i have AGAIN the transaxle aout of the van, this time, i remove all the stuff in about a day (well, this time i know how does all things were removed, so it was very much faster) and i have open it again.


finally, i saw the problem, and if i should know it before i could save myself much money for the tow truck.

well, the problem was a bad assembled direct one way clutch, it was not making contact with one clutch disk, so it was more "outside" from it place, this causes, an excesive pressure over the low one way clutch, and to become overheated becuase it makes much friction with a plastic washer. So when i tried to separate the overdrive drum, it was very dificult, but finally i saw a plastic washer, completely melted because of the friction and well, that causes the one way clutch to doesnt turn free in the direction that it should turn free, specifically it was in first, and reverse so that was the cuase of the correctly function when first started, but after the first drive, it started to fail.


well AF friends, i will keep you informed, but by now i have just to buy a friction disks package(becuase it become damaged cause of the stucked one way clutch), two new plastic washers (because of the melting) and a new gasket kit for the rebuild. well also the 12 quarts of Mercon V but that is tha last thing.


PD:I have in my own varios manual about dissasembling and assembling the Axode and family transmission, apliccation charts, etc; this are in PDF formats and are from the ATSG and transtec, if you want it just send me a email or write a post requesting it, i can say that they were very usefull for much specifications (the problem was that i doesnt understood varios terms of the manuals because there are in english, but they are very useful.


Greetings and thanks for all your comments
