Transmission Issue: Engaging Drive
I thought it would be a good idea to run this by the community:
I had a 2000 Dodge Ram 2500 5.9L V8 (Gas) with an automatic transmission. A few years back it began to slip slightly in reverse. I took it to a transmission shop and had a basic servicing performed. Specifically I had the bands adjusted, fluid and filters changed, and ended up getting a new transmission pan. This solved the issue.
I've since replaced it with a 1996 Dodge Ram 3500 5.9L CTD (Diesel), also with an automatic transmission. Just for the past few weeks I've noticed that sometimes when I shift into drive it won't go. If I fiddle around with it, dropping it into 2D or 1D and then back into drive, or into and out of neutral, it eventually engages. I thought I'd do the same thing and have the transmission serviced, bands adjusted, etc.
The part where I'm blurry is when the shop told me that a servicing probably won't solve the issue. They said on the early 47RE there was an issue with fluid circulating back (not sure where they are talking about) and that there was a retrofit kit to replace a return line.
They also said that there is adjustment for reverse (the reverse clutch?) but not for drive, and that was why the servicing would work for the reverse gear, but not for drive. Does anyone know what they are talking about or have an opinion about whether this information they gave me was accurate?
This is a new shop for me. They come very highly reviewed but I am leery of new shops and being taken for a ride. Unfortunately, they are one of the only shops that will service transmissions in the area. I've moved since the 2500's servicing and thus that shop isn't an option.

So far as I know, the 47 series transmissions are just beefier versions of the 46, and a lot of parts from the 47 are considered 'upgrades' for the 46..... Hence, there should be two bands to adjust, just like the 46. I bet the trans shop is trying to sell you on a rebuild....
From the factory, the torque converter doesn't fill in park. There is a check valve in the cooler lines, that is supposed to prevent drainback... but, even without that valve, (which lots of folks remove, as it can cause some serious problems as well.) the worst that happens is, first drive of the day, it takes little bit for the T/C to refill, so you get somewhat of delayed action when you first put the truck in gear. (any gear)
So, first thing to check would be if that valve is there or not. Should be in the cooler line that feeds the bottom of the cooler in the radiator, about ten inches back from it. (basically, where it transitions from metal, to flexible line.) Have a look, see what ya got.

I drove the truck for 300 miles last week with no issues, not even when it was started cold. My mechanic said he checked the fluid while he was stickering it and that it didn't show any signs of a problem. He also said he moved it around his lot several times in the past week and had no instances of it not moving after being put in gear.
I'm considering following his advice and not worrying about it unless the issue crops up again. What would you all do? Would you have the transmission serviced anyway?
