Hey all, So ive got a billet triple disk converter and a billet stage 3 transmission express heavy haulers trans with high pressure valve body upgrade in my 03 2500. I live in northern Canada and we had a nasty cold snap a few weeks ago and it caused my pan to start to leak on start up a tiny bit. So i bought a new pan seal, filter and some fluid, dropped the pan put new seal and filter in cleaned the pan and filled her back up. I overfilled it a tiny bit and realized after i was cleaning the shop that i forgot to put the magnet back in the pan... oops. Decided id leave it for the night and drop the pan again the next day. However on my way home from the shop it started slipping in overdrive going up the hill. Assumed it was just from over filling it, so i pulled the pan again and changed the fluid and put the magnet back in. noticed that the fluid looked a little dirty and there was a bit flakeyness in the bottom of the pan which seems not so good for only being in the trans for a day. Anyways cleaned it all up and filled it back up with the acceptable amount of fluid but it still slips overdrive! Havnt had a single problem up until i did the service, find it hard to believe that running it without a magnet for 24 hours would have caused any real damage so im a little worried and a little confused. any thoughts are much appreciated... hopefully i dont have to pull this trans again lol. Was doing some reading through old threads and saw bit of talk of the tps acting up and causing similar problems but that seems like a pretty weird coincidence but im not really sure.
