My friend has a 1997 Ford F250 diesel that the automatic transmission appears to have gone out?
It was working fine, never slipped or acted up at all.
He parked the truck and it was fine.
He got back in it to drive it and put it in drive and it is slipping really really bad. Will barely pull itself. He puts it in reverse and the same thing, barely will pull itself, slipping really bad.
I have never seen a transmission go out this fast. Usually they slip and act up, but this one was running great and went out with no symptoms of going out? Have you guys ever seen this and any ideas what it might be?
It was running fine and with no indications of problems went out after he parked it? Need Help with this one. Thanks

 

being in the tranny buis since 1977 I've seen this a 100 times,it's good then it's no good,if the fluid is up, sounds like it's tranny time & replace the torque too,good luck,Gigger

 

I have a 97 F250 , The shift lever selector tube was replaced not long ago. However it needed to be changed for about 5 months trouble finding gear to start and park. Now I was finally able to be without transportation for a few hours and thank God, not to much money. Now since the indicator or selector tube was changed I have noticed that not all the time but lots of it that when my truck (automatic) shifts there is a type of low rumble like a bad patch in the road after it engages and once in awhile a clunking noise. Oh it is a F250 SD turbo Diesel 7.3 with 320,000 miles, I have no clue as to what kind of tranny. What could be the problem?

 

You checked the fluid level.

 

I have a 97 F 250 7.3 4x4 Auto trans. 201k miles. Took factory orignial trans out 1k miles ago. .Found another -97 identical to mine. I bought the whole truck and drove it for 3 weeks drove great and shifted fantastic. We removed the trans and computer from the donor truck and placed it in my truck. After three days it starts shifting hard going into second and ocasionally third. Scanned for trans codes .... NO Trans codes. I"m stumped .... speedometer is fine. NO codes in truck at all. What could cause this. It drove great in the other truck. Remember we changed the trans and computer.... Please help

 

I'm just guessing here but there might have been some crap in the cooler unless you flushed it out before installing the new trans, maybe a fluid flush or change will help.... is there a local trans shop you could talk to.....

 

My guess is that there is a wiring or sensor issue with the truck. Installing a new trans didn't fix the truck issue so it still doesn't work right.

The most frequent reason for no codes when there is a problem is using a non-compatible scan tool that can't read trans codes.

 

We did flush the cooler prior to install new trans. I guess i can take it to another shop and have them check for codes. Is there a particular scanner that i shoudl use? My friend had a new snapon... it cost 14,000.. will that do It?

 

What ever Mark says is what I would do, yes that scanner might do, ask the guy that owns it...sorry I cant be of much help

 

Gosh I am not sure which reply is for me...But, believe [{Did I check fluid ] If so, Yes, that was the first thing I did. The problem has become a bigger issue now. Or maybe a whole new problem... When the original problem starts I noticed the overdrive off light illuminates on my shift lever tube end. When this happens if I disconnect both batteries it goes back to good. I have to do now and then. Then it happened like 3 days apart. Did it again disconnected the batteries reconnected and now the truck will not even start. My water in fuel light has been coming on s teady and I have been draining it steady but as soon as I get back in and drive wif light comes back on. When the truck wouldn't start the wait to start light came on like it should and went off like it should. but would not start. I removed fuel filter and there was no fuel I drained the bowl without the filter and there was a bunch of dog **** looking stuff in the bottom of the bowl, I removed the filter stand and lifter the heater plate off to the side, I didnt disconnect it (not that brave yet) and cleaned the bowl out. Now this yellow metal plate I am assuming is the fuel heater has a circular wire with 3 round tabs on it. I noticed the first coming from the wire side is adhered to the metal plate but the second and third (last) are not connected to the plate and there appears to be like surface rust under the 2nd & 3rd tab. Could this be the problem@ should all three be adhered?

 

Yes this is the first thig I did
