Bad tranny or torque converter?

[JJR]

I have a early 99 with 93,000 miles on it. Truck just started having tranny issue. Truck still shifts good and firm most of the time but I'll be driving and get a double shudder and then it acts like it is slipping in 3rd and overdrive or won't shift in od. Turning od off makes it worse and the engine just seems to rev to 3000 rpm where it kind of catches. Stop put it in reverse and it still kind of slips until it shudders or clunks again then every thing is normal again with good firm shifts until it clunks again. I am thinking something in the torque converter is letting loose. What do you guys think? It also sometimes clunks in reverse on first startup. Tranny does not run above 180 degrees and fluid is still red but like I said it just stared doing this but seems to be doing it more often.

morning bump. Also truck shows no codes.

Drained little bit of fluid out of torque converter and tranny pan. Has a metal smell and a backend red tint now. Truck also has a noise at idle that sounds like a secada or locust bug but goes away when you touch the throttle in gear.

My money is on tqc replace it before shavings go through the rest of the tranny

im sorry pal but get ready to purchase new transmission. either way. Once it gets to that point of limping home it is shot 9.99 times out of 10. I put two autos in mine before swapping to manual.

Been doing some research and would like to check center support bolts. don't exactly know what to take apart to do this. I know it is up in the valve body some where. Any one done this and have pics or just a good description, things to look out for? thanks.

The noise at idle is for sure tc. The shifting problems are probably from metal from tc getting into valve body. Don't worry about the feed bolts. Not your problem and too far into the trans to worry with.

Well finished putting trans back together today. Special thanks to Fordnutz for giving me some pointers. No more noise or shift problems. Everything in trans was pretty clean so I felt good about the clutches. Hardest part was popping the solenoid pack out (dang that o-ring was stuck). Center support bolts were not finger loose but did take a full turn to reach spec. After this I pulled them out cleaned them real good and applied loc-tite and retorqed. Flushed all fluid and so far so good. Pretty easy process and seemed to pay off.

hey can I ask what manual you used to put the valve bodies back together? Specifically the check balls. If you can post up a link or just tell me what to look for. I have my valve bodies off but need to check my feed bolts today when I get home. So does your tranny work now?

Works great so far. Pm semt.
