Message: [QUOTE="Kylerf150, post: 703624, member: 4897"] -------------------------------------------------------------------------------- Hey guys I could really use some help and input on my problems I have been having. About two months ago I put in swamps 200cc injectors in my truck with their tuning. My Ford HD tranny w/115k went out about 3 weeks after the injectors. I installed a stock used tranny with 88k on it and it lasted less than 3 days. I purchased a Heavy duty billet built transmission from one of the highly recommended tranny builders ( I don't want to mention the name because I don't want this to turn into a BTS v.s. Woods v.s. Suncoast v.s. ATS debate) It was a great choice and I know the builder is going to take care of me. Anyways my question is all three of these transmissions went out in the same way and I am wondering if it could be a pcm/ tuning problem causing the failures. Heres how it happens Tranny #1 115k The 1st transmission (HD Ford with 115k) went out while I was climbing a fairly steep hill in the middle of a hay field and just started slipping. I started to head back to town and it didn't want to upshift into 2nd gear it just revved out in between 1st and 2nd. I let off of it and it shifted and shuddered really bad I am surprised I still have a rear end.I made it about 3 miles and I lost all forward clutches and had good reverse. Tranny #2 88k I borrowed this from a good friend to try and get me by until the builder could get my built tranny built and shipped up north to me. Well this tranny lasted about 3 to 4 days less than 200miles and it went out pretty much the same exact way. While it went to upshift it slipped going up a on ramp I let off and continued about 800yds and it started slipping and shuddering really bad on the highway. I lost all forward gears and had reverse. Tranny #3 Brand new Billet shafted built to the nuts Tranny 150miles Well I got my awesome new tranny and it was working great until I hooked up a load of cows and started to haul with it. I didn't feel any shudder while pulling,good firm shifts it was pulling great and I was happy. Until I started up this steep a$$ hill It was in 2nd and as I was pulling the hill it went to downshift to 1st and it SLIPPED in between shifts. I made it probably about 5 more miles to the next big a$$ hill and I put it into 4LOW and made it about 200 yards up the hill and I lost all forward gears. I put a pressure gauge on it and I was getting 190 psi stalled in forward gears and around 300psi in reverse. While I was stalling it and checking pressures The Front clutches seized together giving me forward in N D 2 1 gears and of course no reverse because it was fighting the seized up forward clutches. Anyways now you know the story The highest I saw for temps was about 185* to 190* on all three trannys. The builder said the pressures match exactly where he would like to see them but my only concern is I can't replicate the 1 to 2 shifts to see if the pressure is doing anything funny there so that is what has me worried at this point. I am thinking that maybe the tuning is causing the problems just because swamps has a lot of tranny tuning in with their tunes. How does the computer control the shifts? What should the psi be doing when it is shifting? COULD this a Pcm problem,or a tuning problem? Should I go with a stand alone Tcm like a trans commander or Co pilot? What are your thoughts as to what this could be? Sorry for the long post and Thanks for the help in advance.
