Rough torque converter lock up and weird delay

Rough torque converter lock up and delay

Ok, i did a search before i posted this and i got some what of an answer, but my search left me with some more questions.

When i accelerate in my '94 F-250 I can barely feel my torque converter lock up, but when i am driving and let off the throttle and get back on it, what i think I am feeling is the torque converter lock up and it really jerks the truck around. This rough lock up is worst around 45 to 65 mph. Its not so bad when it happens when i am going slower than 45 mph.

Also, when i start from a stop, i feel a slight shudder and a delay before the truck starts moving. If i give it time to start moving on its own with out my foot on the throttle, and then proceed to apply throttle, it doesnt do this.

Is my torque converter on its last leg? I have no clue if it is stock, is there a way to identify my torque converter?

any input is appreciated
Thanks guys!

Im bumping this back to the top.

I hope someone can answer at least one of my questions.

I had problems with my 93, including the shudder. All of my problems were inside the TC.... I believe. Besides the solenoid pack taking a dump on me, I never had E4OD issues in the tranny itself. Only in the TC.

Sounds like the TC for sure.

factory TC isn't bad on price but its junk. i wish i would have had the money to get a h.p. but i just didn't.

ok, well, i sure hope it doesnt let go soon.

I noticed my tach was bouncing around really low in the rpms, so i think my tach sensor is going out too, maybe there is some relation. I tried cleaning it but it didnt do anything, it still reads really low.

Is there any way to identify the torque converter? mine is blue with no drain plug.

The converter is aftermarket. The tricky part is no drain plug. It could be a single disk or a multi disk lock up clutch. Stock Ford converters are unpainted and have a drain plug pre 01.

If my torque converter is going out if have two options. One, find a good new torque converter. Or tow, find a ZF5 and do the swap, i have always wanted to do one anyways.

What would be a good company to get a torque converter from? All i know of is ATS and suncoast.

I had Kawano's Transmissions do mine in San Jose, very happy. He's buds with Towcat. Being so close to me, and easy to deal with, I wouldn't use another. If my buyer tomorrow doesn't show up, or passes on my CC I have for sale, I will have a complete ZF5 swap set up you can pull from it.

I will recommend this guy for a good converter. www.racerxautomotive.com

What is the advantage of a triple disk torque converter?

More surface area so the TC locks more positively with less likelyhood of slip.

ah ok, thats what i figured. It is also less likely to fail, right?
