alrightly boys its cost me alot of money and even more down time this past year but i now have some confidence in my new transmission and engine ! as some of you know last april my problems started when i blew 2 drive belts within 3 miles , after that the transmade alot of noise . i sent it to my local dealer and they assured me that they compared the noise to a brand new machine and it was the same even though i asked to have the trans removed and inspected at my expense if nothing was found ..... they put on a new belt and charged me for it ! so less than 150ish miles later the noise finally showed itself in the form of a gernaded trans and junked motor . luckily it was replaced with a new short block from AC which included new style cases , higher oil pressure . but we were unsure at the time if AC had changed anything in the trans . according to the parts schematic they were still using the same crap thrust washers in the origainal trans .
Well due to some very unfortunate turns of events my motor had to be pulled yet again after 46miles on the new short block , ( ie.install and assembly error, is all ill say)
i sent the whole motor trans and clutches to D&P PERFORMANCE and had the m tear it down to bare block and check it over , repair and replace anything that even smelled funny .
when D&P open up my trans at first thought it was missing pieces . but after 3 days of phone calls the AC they got a answer ! guess what AC knows they had a problem with their transmissions and redesigned the entire thing !
no more crappy thrust washers, larger shafts and gears, improved oiling . quote from my builder " very nice piece" .
unfortunatly at this time there is no parts schematic available for anyone to veiw , even the dealers , we have a part # 0801-182 and the earliest build date code for the part # is on my motor that i have found . im sure there is others but i havnt heard from them . that date is 8-19-10 . from what we have found out this transmission is what comes in the all 2011 XTZs . AC has yet to update dealers on the change in parts or when exactly they started using this trans . but expect to release all info parts releated with in the up coming months .
right now the only way that we know to get the new trans is in the new short block and assuming in a new complete motor assembly . if you look up and transmission for a 2011 on parts program it will show you the new stlye cases and the second gen of the trans which has the new counter shaft assmembly but still uses the washers .
and if you look up the shrot block 0801-182 it will say that it replaces #0801-186 which is the old stuff . and it will refer you to the old schematic for the 0801-186 .
i asked D&P if there is anyway to tell the difference visibly from either engine and they said nope . you have to open it up and inspect the transmission .
so just a recap of what we know then
if you have had a short block replaced with part #0801-182 you have the new style cases ,higher oil pressure and the new design transmission
if you have a 0801-186 you have the new cases , higher oil pressure and
the old original trans mission with the updated counter shaft .
i wish i had a parts schematic to go with this info and an exact date when AC started using this trans in production machines but not even the dealers know ......and hopefully soon we can get some more .
talking with D&P , we are assuming that with the redesign in the cases and oil pressure that it came before the new trans and that anybody with a trans failure can order up a trans assembly and it will be the newest design , but we cant be sure yet .
i do know that if you had a failure on a 09 early 10 xtz you had to buy and update the counter shaft assmbly to the 2nd gen trans that still used the washers , but that was also for the gen 1 case .
i hope this helps any of you guys out there and if anybody has any more info on this wed love to hear from you . i know between finding out about this and having one of , if not the best shop in the country go though my motor i am gaining confidence back in my machine and AC
