Hey to all. I been reading a lot on here and when I find one thing I think that's it then read something else. I looked in the search and talked to a few people but want to ask. Ok I have a 79 Scout II with a 345 and a 727. The tranny isn't right it takes awhile to start moving in gear and slips out of 3rd. I heard its the bands out of adjustment then I just read it could be the kick down cable. I'm not a tranny guy so any help would be much appreciated. Please give your input and thoughts on what's wrong. Thank you

As for your particular issue described, what needs to be done is a transmission service.
A transmission service means...dumping the current load of oil and discarding in an appropriate manner. You must carefully inspect the debris which will be found in the pan and post pictures if you want help in making an id of the larger particulate.
Then do an r&r of the filter.
Finally...perform a complete band adjustment as described in this thread:

No doubt if that transmission has not been serviced in many years, the shift tower seals (n=2) are also leaking, now is the time to handle that detail also:

After performing the band adjustment, then verify correct "kickdown" linkage adjustment, we've discussed this over and over in this sub-forum. Adjust the throttle cable first, then adjust the kickdown linkage after doing so.
Periodic maintenance is required for any automatic transmission, the oem maintenance cycle was very conservative...but the vast majority of the ihc version 727 units still in service have never been properly serviced, these vehicles are 35+ years old!
If...after performing all the above recommendations, the transmission still has issues, it's simply time for a rebuild, no way to bandaid something that is worn out. What you describe is extremely common regarding any automatic transmission, not just a 727.
