Well, its been about a year, but i found a wiring harness to take care of my electrical gremlins to some degree...so thats nice, but the bad news is the transmission issues do not seem to have been related. The car is a 2006 Dodge Magnum RT named Luna that I love very much, coolest car I've ever had, and if I can help it i'll be dead before she is.
The story so far. My engine was damaged about 2 years ago, so we had a new one sent over from summit, one with a built in cam, the hp103 from ATK. After fixing all the problems the mechanic who installed her new engine caused (missing bolts in the trans case, water pump fitted on with gasketsealer, etc) I basically got to enjoy her for all of a few weeks before the torque converter gave out. Being unsure if it was the TC or the trans, and having very little trust left for anyone, I Rebuilt the trans, bought a rebuilt high stall torque converter from trans_one (ebay, i know, im not too smart i guess lol) that they said stall tests somewhere from 2900 to 3200rpm. Ever since getting the transmission back in she's been giving me limp mode, she kicks back p0730 and p1731. basically since then I havent had my car working. Ive tried making some setting changes of my own, but my knowledge of the transmission settings is basically nil, bought myself a supposed course to try to LEARN it... it didnt have anything about the transmission tuning side so that was a waste of 500 dollars, took her to a local shop, sincity something to have THEM tune her using their dyno since its obvious i'm out of my depth, she went in there 3 times and came back with the same issue, and whatever they did to her VE tables had her way off of stoich, like 20%...its almost like they didnt bother using the wideband and just installed a canned tune. Basically at this point, I've got serious trust issues for "mechanics". So, back to square one. I was having some electrical gremlins so i just gave up in the dead of winter until i could source a new wiring harness, since my attempt at personally rebuilding it caused more problems than it solved, I probably connected something incorrectly or messed up a solder joint...either way, new harness is in now and most of the electrical is fine, but the codes persist, p0730 and p1731. I'm not sure if theres just something wrong with the torque converter, something STILL wrong with the transmission, something wrong somewhere else... i've changed the solenoids, i've changed the electrical board in the trans which i'm spacing on the name right now (been up all night), Tried replacing the speed sensors in the wheels just incase those were reading wrong, tried a new tcm at one point but put my old one back on since that didnt fix it, tried a new PCM and naturally that didnt either. I'm definitely not a wealthy man, being disabled doesnt pay much thus why it takes so long for me to save and get parts to try to get this thing working, i'm not sure i could afford to have a shop look at it if i could even find one that i'd TRUST at this point, because frankly they just keep being TERRIBLE, and im thinking that its just that i've always lived in las vegas so maybe there just ARENT any trustworthy mechanics around.
I need some help.... and you guys are probably the only ones that could help at this point. I saw someone named TransGo Robert on here commented on another thread with the same problem and seemed to know what was up so I'm hoping him or someone with similar expertise can help, and so I made sure to grab all the transmission sensors it would let me for the logs I've attached as he mentioned to do in that post. I've honestly searched through basically every thread on here with the error codes that i could find, but either didn't understand what was being said, or it didnt have a solution, or the solution just wasnt apparent from the thread. Could this be a PHYSICAL problem with the TC? Could it be just tuning related? Did I somehow screw up following the rebuild manual for the nag1 (i was extremely careful to follow it as perfectly as i could but its possible i guess)?. If its just the transmission I know a yard that has some "good" junked ones i can get ahold of that probably wouldn't take so much money that it leaves us destitute, or if its the torque converter mechanically I was considering just getting another high stall one but this time from the guys at HHP so I would KNOW it was a good TC, but if its just tuning then I'd really love to have my car work. I wanted to get a higher stall because i felt like itd match up better with the expected performance of the new engine than the default. The only other thing I can think of to do is just to buy a normal "working" trans and normal tc from a salvage yard, but having put so much into her, rebuilding the tranny, brand new frictions and everything...all the seals, all everything and all that work, itd just be a horrible shame to throw someone elses dirty old slushbox in.
Thank you for any help you can give, this has honestly been a real living nightmare, and i'm just hoping it'll be over soon and I have my girl back on the road.
