So being a 94 it doesn't really have OBD and I don't know why they were no codes in the memory so any time I parked overnight it was ready to go in the morning like it reset itself I never disconnected the battery but was prepared to do so so I had to really good shops put there Snap-on scanners and neither shop reported any codes only the day that I change the throttle positioning switch did we get a code for that so all that aside it was definitely the overdrive that was messing me up after about an hour and a half you see I was in Pennsylvania and it's just one Hill after the next and I suppose the transmission didn't like what was happening maybe it was slipping and then it would really mess up sometimes with just first gear say this really nice transmission shop and this guy named Dan told me to turn the overdrive to the off position with ignition switch on and then start the engine and drive at 50 miles per hour and it works and so I approached the interstate and at the very last second I chickened out I was on the ramp to go north to the Great Lakes and all through Michigan and so forth but I turned South and went home to Virginia 500 Miles no problem each time I stopped I had to remember to turn the overdrive off however I could feel a little shimmy in second gear so maybe I just got home with a bit of luck or maybe there's another 50,000 miles left in that transmission if I stay out of overdrive maybe I should pull the pan and look at the filter and if there's no parts wearing other than Maybe a little burned up fourth- gear material also I added 3 quarts of transmission fluid and one quart of non-slip from Lucas maybe the extra pressure helped get me home

 

So the 175 temperature was on a day when I did not even go into 4th gear and I'm just assuming the burnt smell which was awful was coming from some friction Heat and it definitely smoke the fluid but maybe never overheated the transmission just the slipping caused it to go into limp mode

 

After 3 decades of automotive engineering experience and a few years owning an automotive repair shop I still believe that new fluid is ALWAYS better than new fluid.

It won't fix the trans that is already damaged from neglect. Too many people wait to change their ATF until the trans has problems. Then they change it and the trans fails. Now they blame the failure on the new fluid, not on the damage they caused by neglecting the trans for years. New fluid didn't cause the failure. It just couldn't prevent it.

 

If It reset itself that is good. As long as Dan said you might burn it up if you stayed in first gear he knows something. Dan may be incorrect about a few things but he sounds very nice. Glad you made it home.

 

The 1994 F53 460 does have OBD.
It is OBD1, maybe the Snap-on scanners can not read OBD1 but other scanners do.
Both codes and data.

A freeze frame of data from a 1994 F53 460:

Yeah there was a scanner and it was reading some information you know I think it was coming over as voltage and then that was translated to temperature but all that's irrelevant because at the time of that test I had not gone into 4th gear that day the shop was only 25 minutes away there was no open Highway and without going into 4th I really hadn't cause the transmission to flip out yet but later that day an hour and a half in 4th gear on Pennsylvania highways transmission slipped out

 

I think if you get all that 4th gear stuff out of the transmission pan then it might clear the problem. It won't be able to go into O/D because it is gone so you don't have to be bothered by having to remember to reset it every time you stop. Sounds like you might have got lucky. You might call Dan and ask his opinion.

 

overdrive is still there and I used it a few times on downhill sections only and a little bit into flat ground but never uphill or under any kind of load at all I'm guessing those clutches are very weak and worn out

 

Start over and tell us what happened. Be specific.

Did the transmission quit pulling in overdrive? Do you have a tachometer? Did the revs climb like you were in neutral?

Do you have a transmission temperature gauge? What temperatures did your transmission reach and how do you know?

Burned fluid is the only problem you have clearly defined.

 

exactly what you said the RPMs went up I guess they call that a flare and what was happening is in the mornings when everything was cold like 60 degrees overnight I would go for a good hour and a half with everything working fine and then it would flare and act like it was not even connected to the engine and of course I had it checked a couple of times but the main thing is the advice I was given got me 500 miles back to my home I did notice it kind of skipped from first to Third at least twice maybe three times so 2nd gears not in very good shape and 4th gear slips after everything warms up after an hour and a half of driving or should I say 12 when it starts to warm up in the day. In reality I'm probably not going to go out on the road again I only have 3 gears and second gear is probably worn out so I do have a 91 F-350 diesel with low mileage and I think I can use that transmission because the truck is Rusted in half

 

What kind of truck is giving you the transmission problems? Is it an RV or a truck? What motor does it have?

 

Guessing you are talking about an E4OD.
A E4OD out of a diesel will not match up to an F53 460 engine.
A E4OD will not work in an F53 unless it is out of a 4X4 truck.

 

my 91 F-350 is a 4 x 4 I was hoping that transmission wood work I'm assuming the bellhousing would need to be changed I don't know if the bolt pattern on a diesel 7.3 IDI and the bolt pattern on a 460 gas are the same I would guess they are not

 

They are not the same. And you can't change the bellhousing, it's a one piece case.

 

The E4OD is a one piece transmission so you can not change the bell housing as it does not have one as such.
As I understand the bolt pattern are different from reading on this forum.

The E4OD.
