So it seams like where the shift lever is in the movement
What shape is the cab mounts in, if rotted and the cab has dropped this would move where the shift lever puts the trans in gear.
Now the mounts, rubber & the metal "bracket" may be good but if the floor is rotted the cab mount would push up the floor.
So you may want to pull the rubber mat or carpet back to check the floor pans, yes both sides, out.
I am thinking the shifter is out of adjustment when in D
Only thing I got ATM

I do have a question for MAX or others with AOD.
If put in D, where 2 use to be on the C4 / C6, I guess it dose not start off in 2nd gear like they did?

Correct Dave, the tranny will have 1st to 2nd/D as a normal auto will do. When D is selected.

question for OP what fluid was used?

I would check worn parts as Dave suggested.

 

I took the truck for a drive today to the junkyard, the old 54" steel lawn roller, finally rusted out and was no longer weldable. I got the roller from someone's lawn, they were selling it, about 12 years ago, think I paid $50 for it.

I took notice of the way the AOD shifts.

Leaving my street, I left it in D, gave it a little gas and the shift from 1 to D was nice and gentle. Got to the end of that street, put the AOD in OD. Made the left turn onto the state road, it's a curve slight uphill, engine still cold. The shift to D was gentle, and hung there, as the up hill curve, was going about 35mph, tranny stayed in D. After getting up to about 40mph, and letting off for the next curve, the tranny went into OD, smoothly/gently.

Didn't pay much attention over the next few miles of stops and hills and curves.

Leaving the junkyard, onto the state road, I gave it a little more gas (maybe slightly less than half throttle) than earlier in the drive, the shift to D was firm, but solid. A few miles later, when turning onto the street my street is off of, the shift to D was smooth/gentle, left it in OD, rolled down to my street, lifted off gas, the shift to OD was gentle, turned on my street, the shift to D was gentle.

There is an uphill on the drive to junkyard on the state road, the tranny smoothly down shifted as I gave it more throttle, then gentle shift back into OD.

FWIW, maybe a good laugh, here's the roller.

 

Up there in New England you should be use to rust and fixing it
Heck you could of cut that rusted end cap off kept the axle and tipped the drum up on the closed end, center the axle and fill with cement.
It will never rust again and would not need to fill with water for weight again

We did some welding repairs a few years ago. My dad had a solid cement one, but it was hard to move around without a tractor attached to it. My son has a plastic one, that he hasn't used in ages, I'll grab that one later this week.

I did think about keeping the tow-bar part... but that's just one more thing I'd have to find a place for, that I may never use.

When I was paying attention to the AOD tranny shifting, when it shifted from 1st into D, my thought was, just like a power glide.

 

Just to clarify, this issue isn’t only when shifting on fly. From a stop if you put in D, you get the rough and late 1-2 shift. From a stop if you put in (D), you get normal shifts

 

Just verify what fluid was put in the tranny ? Was it Mercon V ?
I'm not an expert on automatics...If the linkage is not worn or lose, to me, your issue is hard to understand why.

I'll assume you've seen the "related threads" below ?

 

this is the fluid im using. Changed about 6 months ago, only driven about 500 miles. Used this same fluid on another aod with no issues. I think my issue is in the valvebody but don’t get how it effects D but not (D).

 

Thinking back, I want to say there was some thread last year about fluids and AOD's. Made me think at that time about going out and buying up lots of Walmart Mercon V.

Do you have an old transmission repair shop around you ? Maybe talk with them about these older tranny's. Or find an auto repair shop that has lots of older vehicles around it. I don't know your area, but around here, they are not that hard to find.

 

Also not an expert but would also say the problem is in the valve body.
Why it works in (D) and not in D is the fluid is going through different channels is my thinking.

I asked google,

We’re going to find out if it’s valvebody related… got remanufactured unit on way.

 

Please take pictures, and we'll be waiting to see how this works out. Good Luck.

 

Will do.

 

Welp, the new valve body seems to have fixed the shifting problem. It now shifts the same in D or (D) but after driving around for about 30 minutes, ATF started pissing out of the front bell housing
