Column Shifter and Truck won't go after coasting down a hill

Whats up guys.

I just picked up a 1991 Ford F-250 7.3 IDI 4x4 automatic and I'm stoked on this being my first diesel. I've got a few things i need help with:

1. The column shifter is super sloppy and will not sit snug in Park, Reverse, Neutral, etc. I've looked all over these forums and cannot find the right way to fix this. On another website they were saying hanging a 3 pound weight on the shifter and then getting under the truck and undoing the shift cable to the tranny and tightening it up that way. is this correct?

2. When i'm coasting down a hill and then give it gas to go up an on-ramp for the freeway, the rpms will rev up but the truck won't accelerate. Half the time after a half a second, the back wheels/lockers bite and then i go. The other times, i back off the pedal and gas it lightly, it seems to catch. What is going on here?

3. Also, when i pull into work, we have this driveway that is on an incline. So i'm clear.....what i do is coast into the driveway and then gas it to go up the driveway. well the truck does not go, it acts like im in neutral. i hit the brakes and then gas it lightly and then i chug up the driveway.

4. in our parking lot, there are speed bumps. i'll hit a speed bump and then the truck acts like its not in gear anymore. I think it might be an electrical problem. I heard something about a neutral safety switch but not sure if the 1991 had one or not.

Thanks for your time and expertise. Cheers!

The first thing I would do is check the oil level. It sounds like it is a littler low.

1) No. That's for '92-up steering columns. Yours has no cable. Click this & read the caption:

The adjustment is probably in the middle of the shifter pushrod, between the column & transmission, above the front driveshaft. There are also hard plastic bushings at each end of the pushrod that can wear & become loose/sloppy. I think replacements are still available.

2,3,4) I agree - that's a classic symptom of low fluid. How old is / how many miles on the current fluid & filter? What brand & type is the fluid? Read this & the NEXT several captions:

You should put all the truck's details into your signature so we don't have to go looking for them:

The proper way to check the tranny oil level is That the truck is running and in PARK or NEUTRAL and Tranny is HOT. That 14 quarts of oil can expand considerably making it an OVERFILL which is very bad on an E4OD.

Yours is not CABLE driven, it's thru shift rods. Put the tranny in Neutral, climb under and check the NEUTRAL lines marked on the MLPS for lining up. SEE pic.
As Above, check shifter rod bearings. There is NO SAFETY SWITCH as such, only a Manual Tranny has one.

If the Rod bearings are OK and MLPS lines are lined up and the oil level was extremely low, the COAST CLUTCHES clutches could be worn out.
