Any chance this is an E4OD? there is a "shudder" problem caused by converter lockup slip due to low apply pressure.
and here is the magic voodoo part - there is a little red 4oz? tube of shudder fix you can get from NAPA that you pour in, drive a couple of apply cycles and bingo - its gone. I had the same problem in a I6-E4 combo that was driving me nuts. I poured this in, drove, first lockup - no change (after about 4 miles of warmup) then next apply I swear it was attenuated. Next lockup after that - gone for good. Costs about $6 or so. 'Dr tranny shudder fix'

I have fixed many of these buy changing the fluid.
What happens is that the fluids lubrication property's break down and the converter clutch cant apply smoothly.
The tube of shudder fix works like the additive for limited slip differentials.
I have also used GM's limited slip additive in the AODE and E40D transmissions with great results.

Thanks again, quaddriver the shutter fix from NAPA sounds like the same stuff the tranny shop guy was telling me about........ I have to work Saturday, hoping to give it a try next week........ if that doesn't work out I'm off to Harbor Freight. gweed I've been wondering about the transfer case...... your picture answers that question.

Is that HUGE torque converter
? How much it weight? 80 pounds? I swear I never saw one but saw lot which is half size which is GM torque converter
I can see why you didn't want remove transfer case because stuff is heavy.
Is auto transmission use vacuum hose to work? If it cause shutter that mean vacuum's pressure drop and up rapid? Do you have vac gauge? Hook to that and try drive. Did gauge stay 15 to 25 during drive?

I dropped them both as a unit, because I just did not want to mess with the xfer case. It was a really heavy, large unit.The most difficult part is re-aligning the tranny to the block. I found out the cement slab that I did it on had shifted over the years and sloped to one side by less than a degree. Once I took out the last bolt the whole assembly just started rolling untill the bell housing hit the frame, as you see in the picture... So yes, it rolls...
EDIT: I had no shutter before, So I cant really say if I fixed it or not...

Milwaukee1979F150, thanks for the reply. I have a vac gauge...... I don't know anything about auto trannys, but I think everything is controled by the computer. You're right, that is one really HUGE torque converter........ never noticed trhe grammar, I from Kentucky.

I don't know but I thought transmission use electric and computer but I read other thread it say it have rubber hose which is vacuum hose so I thought it could cause this but I am not sure.
let us know if vac gauge not stay steady.

Milwaukee1979F150, I'll check for a vac hose..... looked at it earlier tonight, but mostly trying to figure out what to use for a pan so I don't soak the driveway with transmission fluid.

Iantiler - Wide, shallow plastic storage bin. Like 3x4 feet. If you are super paranoid about it, put some painters plastic down and cover it with cat litter or dirt (dirt is less plesant, but absorbs the liquid.)

gweeds, thanks I hadn't thought about the plastic storage bin........I have an old plastic 55 gallon barrel I was going to cut down, but I can grab a bin from Wally world cheap....easier too

itsnotblue, thanks for the reply. I changed ALL transmission fluid and filter.....can't believe what a difference it's made, first day still shudder was still there, but MUCH better, shifts are much smoother. After three or four days shudder is almost completely gone, I'll pick up a tube of shudder first of the week..... just wanted to see what the fluid and filter change was goning to do.

there is a little control module on the side of the transmission pan.
that module went bad. the transmission would shift just fine around town. on the highway, it would be fine for a little while, and then just randomly downshift to 3rd gear...and then back into 4th. you could stop it by turning O/D off at the shifter.
Bronco was E40D with a 302...don't know about the F-150 (had I-6 motor)
