Tranny or torque converter?

22 posts in this topic

So I drove my '01 F-150 auto about 60 miles yesterday pulling a trailer. It was 90+ degrees outside, and when I arrived at my destination, I put my truck in reverse to back the trailer up, and the truck stopped suddenly like I hit something. I got out and I was in a wide open parking lot. I got back in and the truck made a strange clunk, but then backed up.

I drove about 5 miles from there, parked the truck, and ran some errands. I got back in and started to drive. The thing started slipping and making an horrible grinding or rubbing sound. Once I got it over 10 mph it was fine. It continued to do this at slow speed, so I drove the 60 mile back home immedietely. Again, no problems once it got over 10 mph, but still the horrible sound and slippage at slow speeds.

Please tell me that this is a Torque converter problem and not the tranny. You would think that if it was the tranny there would be symptoms at high speeds as well as low speeds. I'm taking her to the mechanic tomorrow, but some ideas would be nice before he tells me a need a tranny when something else would have fixed the problem. Thanks in advance!

It could be a 1st gear valve going out? Just a guess.

Wouldn't torque converter make a noise thru all speed ranges if it was going bad?

I would say if you feel ok with, at least bring it in for a test drive at a dealer or shop. If not someting in the trans, could be transfer case issue (if 4x4) or maybe rear end issue.

Just hate to blow the housing or case on anything and when in doubt, tow it out and into to the shop. $75 tow could save hundreds in further damage.

Good luck and let us know what happens.

Check to see what the trans fluid smells like(burnt,clean).

If it is clean, this may sound odd, but if you have rear disc breaks, check to make sure the lining for the e-brake didn't come apart form the metal bracket.

I have had more than one do this, and it sounds like the trans, or the rear-end is falling apart. One even locked up, and wouldn't move.

Just a thought.

The tranny fluid smells and looks clean.

I do have disc brakes and I'll look at that, but I'm afraid it is the tranny. The spedo even jumps around when I feel it slipping, so that can't be good.

Thank you for the ideas triple B!

If your speedo is jumping around at the same time the slipping is happening, I would be looking at the transfer case. I believe that is where the output speed sensor is located.

I was thinking it could possibly be something with the transfer case. When I put the truck in 4 paw, it REALLY acts weird. All the symptoms are magnified when I put it in 4 wheel drive, and the truck stuggles a little more to move. Would a transfer case cause slipping though, and if so, why?

I made an appointment for Monday at the local Ford dealer to have it looked at. I'm hoping for the best, but I'm prepared for the worst.

If it is the transfercase they are only $80 to $250 for a used one depending on which one you have.

Does anyone know if a transfer case would cause that "slipping" sensation?

The t-case is gear to gear so it would not slip. I would suggest a good trans shop to inspect it. When was the last time the fluid and filter were changed? Making up with your PM every 30k especially if you pull a trailer are key. My dodge has a filter on the cooler line also including the trans pan. Good luck.

Transfer case will not slip. It is operated by chain, you will feel hard jerking and loud banging if some gear teeth are gone.

I suggest a tranny shop too.

There is a problem with some of the New Process transfer cases where a snap ring breaks and one of the gears will slide back on the output shaft splines and intermittently "slip" on the shaft. It makes a very nasty sound like crunching and grinding. This may or may not be your problem.

Thank you everyone very much for the help. I will let you all know how it goes today. My plan is, if the dealership says it's the tranny, to take it to a shop somwhere that specializes in transmissions.

Why not leave it at the dealer, they are the ones trained for the vehicle?

The dealer wanted $3400 to fix it. It's a long story, but my local dealer really disapointed me. I ended up trading the old girl off for an '06 at another dealer.

So, it ended up being the trans? That quote must have been to remove and rebuild?

Well, at least now you don't have to worry about the repair bill. grin

The problem was the trans. The dealer took my truck on trade, and took $2000 of the "trade in" book value. I thought that was ok considering. Either way I was going to be out, and I just decided to trade up. The new truck has less that 40,000 miles and warranty til 60,000 so hopefully I won't have troubles for a while!

I hate vehicles!

    •     They were in all different stages on this lake, was messed up and I didn't know what was going on
    • Good Borch!   I have seen a large up tick of birds locally as well this last.  Although not hunting.   Trying to convince the wife and kids to hit a time or two yet.
    • They can sure humble a person. 
    • Well I tagged out this morning.   I got out later as my daughter and her family were over so I headed out after breakfast.  I drove by the field to see if there were any there so I could plan a route to the blind.   There was a fl8cknof Jake's and a flock of longbeards.  I quickly snuck into my blind and stuck a funky chicken decoy out.  As I was stepping into the blind the Jake's start clearing the trees between the blind and them.  They worked around out front a ways.  Suddenly I see 2 toms fly into the field.  The jakes immediately charged the toms driving them out of the field.  After that the jakes saw the funky chicked and headed over to check it out.  With the toms gone and time dlipoung away I picked one out and shot him at 30 yards.  He'll taste good on rhe grill this summer.   Got in the blind at 10 am and was done by 10:15 am.  It's been a long season. 
    • Fun in the yak today in SE SD caught and released a bunch of these today:
    • How can a bird with brain the size of a pea out smart us!
    • The 2 lakes i bass fish have slowed way down the last week.   A swim-bait ripple shad was hot ticket for a while but that is just a pike attraction right now.  Been switching to a Senko and helped a little.   Pads are coming up fast now and we should see a spike up in activity soon.  Cannot wait to throw the frogs soon as that is the biggest rush watching those eruptions in the water!!   Thanks for posting as i found it to be quite slower than usual also.   Which means i need to find better ammo during those times.  
    • Tomorrow we will be back at it
    • I am giving it a last hurrah tomorrow. Sorry I haven't been able to check in here much. I have hardly been able to get out this year between work, a baby at home, and a recent trip out of the country for a relative's wedding.    Last time I was out I had a real nice Tom within 20 yards after a very long standoff. I think I screwed it up by rushing myself a bit. He stood around 50 yards out literally strutting back and forth like someone had drawn a line in the mud that he wouldnt cross. He must not have wanted to fight with the strutter decoy we had out. He did that for 45 minutes to an hour and finally came our way after a hen led him towards us.    They came past us but were outside the decoys and angling slightly away from us. Then the tom turned and started angling straight at the strutter decoy. That meant he was basically quartering to me and when he was 15-17 yards or so out I drew because in the back of my mind i was thinking if he kept moving that way and past the decoy he would quickly be in a spot I would have had no shot.   In hindsight I think he had realized (once he got close enough) that he would have been able to whoop up on the decoy and he was coming in to do just that. I probably should have waited to see, but I didn't and right as I hit the backwall of my draw his head popped up on alert and he turned around and walked straight away knowing something wasn't quite right. I could have easily shot at him at 20 yards but he was facing away and I just didn't feel comfortable. I am confident I would have hit my mark but I didn't like shooting at something walking straight away when I am not experienced with bow hunting turkeys.   I know some people will say that I should have shot, but I have been bow hunting for awhile and never wounded anything because of a poor shot or poor shot selection, so I didn't want that to be a first. Hopefully I get a shot at redemption tomorrow!
    • Way to go team!! I sure took the avg score down with my jake
