Intermittent hang-up 2-3 shift with my 48re?

[rjohnson916]

Is my 48re on it’s way to **cough** South **cough** Bend? Ok I’ve got this problem that has happened mysteriously twice in about 30 days +/- Symptom: I come from driving off the freeway, stop get fuel. Let’er idle while I fill the truck up at the pump. I use idle time at fill/ups as turbo cool down from driving at speed, I don’t usually if I’ve been just driving around town. Anyway, I’m done pumping fuel, jump back in and take off easy. My truck will take a little to get out of first gear, then it gets hung/up or what feels like it don’t want to shift out of second gear? I kept gradually (slowly) speeding/up and it would not shift out of second??? I get to the next light, stomp on it, to see if she will go through the entire gear range and everything is good and shifting normal. I quickly check the report screen on the edge/ Attitude, keep in mind I’m on (stock) but it’s registering 4% slip. It only did this one other time a few weeks back, I’ve got 28K on a 2005 Truck, 3:73 SRW short-bed Q/C 4x4. I tried goosing it three other times from a dead stop to see if I could get it to hang up again, and It just shifted normally with 0% slip. I’m sorry for not being too (auto-trans) savvy I’m 27 years old, and have had nine vehicles since I started driving, all have been standard transmissions, this is my first automatic ever. I have driven automatic cars that friends and family own, but the 48re shifts way different than any automatic I’ve ever driven, so I don’t know what a bad transmission feels like when it’s on it’s way out. Just need to know if I should keep DTT’s number close by right now or am I getting scared over a common clitch that happens to all 48re here and there?

I have the same transmission in my 05 SRT-10. Mine hunts and hangs between 1&2. The problem is worse when the transmission is cold and only acts up under light throttle. When I stand on it the transmission shifts as normal. With that said the problem with mine is that the 2nd gear band is going bad and the band behaves differently when cold, but is getting worse progressively. Also this has damaged the strut and apply lever, all 3 parts need to be replaced, think teardown for this. This isn't an emergency issue and I was told won't cause major failure, but will get progressively worse till I can't deal with it. Basically just plan on a rebuild in your future, sooner than later.

Thanks JMingledorff I agree my problem happens as aforementioned, and the only other time was first thing in the morning, it was fairly cold i the first couple minutes of driving. I wasn't looking to do a transmission yet, but looks like I will be fore shortly guess we will see.
