      My otherwise very reliable transmission has begun to not shift in the morning when I leave for work. It is fine after about a minute of driving. Any ideas about what is going on? It was rebuilt about 6 years ago. Could I just need a fluid change? I have never done that to it. What do you think?
      Thanks

      Id say flush it, new filter and new fluid should do it. I spent some time in AK and the dudes up there would kick the tcase into neutral and leave the tranny in gear for a few minutes while their trucks warmed up to get all of the tranny fluid warm and running through everything. Just a thought.

      That makes sense, I'll do it and report back. I'm wondering how often I'm supposed to be doing it, anyway.

      How often to do a tranny flush? I'd say probably every 50,000 miles or so. If it's higher miles you might do it more frequently.

      Governor is sticking. Common problem.
      You can remove the tail housing to access without dropping the trans.

      Watch what you use for trans fluid, I have had the wrong fluid recommended. It's Mercon V.

      I ended up taking it to a trans shop I trust. They had lengthened a drive line for for my 68 Bronco years ago and I was happy with what they did. Also I didn't want to change the fluid myself, mostly because I'm getting too old to mouse around underneath it. That, and places like Jiffy lube suck. In short, all is well now. The mechanic said with the pan off, it looked really clean in there, only a little bit of metal on the magnet. Also my computer didn't have any transmission codes in storage. He said that it was obvious I hadn't changed the fluid in a long time (actually I never have). So, I accepted my mild spanking being thankful about the outcome. He recommended some conditioner for it because of my negligence which I agreed to. I have to say, I'm majorly relieved. Note to myself and others: don't ignore this maintenance point. I feel like I dodged a bullet.
      Thanks all for your input and knowledge.

      I hope that 'Conditioner' doesn't result in leaky seals. Some cause seals to swell for a while and while swollen they wear, the leaks show when they shrink back to original size.
