I've got a 2000 f-250 SD with 100k miles on it when my wife was towing a mini van croos country from New England to Washington when the tranny started slipping in PA. When she got to MO the tranny was grinding and making a weird sound. Once on a lift and the tranny pan dropped they found chunks of metal and I'm trying to find out is this a common problem with the 7.3L tranny's? If anyone can answer this let me know also I'm going to be replacing the tranny with a performance tranny does anyone have any suggests or recomondations. thanks for your time

 

Was it stick or auto?!

From leaning towards "the pan"... I'm assuming it is an automatic tranny.

No this is not common.

As far as replacing it with a performance tranny... I'd look for a heavy service built tranny... since you are not racing it.

 

We run a fleet of F-350's with diesels. (7.3's and 6.0's) They tow landscaping equipment all summer and plow all winter. Yes, we work them hard, but we maintain the hell out of them. For instance, I don't think we've ever gone more than 15,000 miles before changing automatic transmission fluid. That said, we've yet to get more than 50,000 miles out of the stock 4R100 that you also have in your truck. Ford recently came out with a heavier duty remanufactured transmission because so many of us were costing them so much money. Actually, I'd say you got a number of extra miles out of your transmission. Sorry for you wife though.

 

The company I work for said they usually get 150K out of a Powerstroke with the 4r100. I've got 105k on mine, and am keeping my fingers crossed...

 

I'm not sure who my warrenty company is by name but after a week of ****ing my wife around and refusing to listen to the transmission guy they ( the warrenty company wanted to have one rebuilt and shipped out taken 2 weeks and the tranny guy said it was best to just order a new one and have it in in about 3 days) they did get a new tranny but then charge me over $500 for because they said they would only cover 5k for the new tranny and the big kick in the ***** is the tranny guy is proir service and didn't even charge me for labor costs because of this but the warrenty company still charged because their inspector had to go out and inspect the truck before and after the work was done and they had the ***** to say they wouldn't have covered it at all but I had an aux. tranny cooler installed so they would cover it because I was trying to prevent damage and wear and tear on my truck.

 

Wow, $5500 for a bone stock rebuilt 4R100 trans? Did they at least give you some vasolene before they got ahold of you? Hate to say it, but you can have a fully built BTS transmission shipped to your door for around $4k. BTS is pretty much the top of the line bullet proof 4R100. Brian actually dares the guys that sled pull or drag race to break his trans. The 2 yr unlimited hp unconditional warranty should speak for that. Heck even a fully built ATS trans is a shade over $5k.


I hope you decide to put a trans temp gauge in the truck now and make sure that anyone who drives it knows to watch it. Most likely if you'd had the gauge when all this happened you'd have seen the needle pegged from heat.

 

$5500!?!?!?!?! Jeeeeeeeeeeeeeezus. I'd like to think that $2500 would build me a stout enough transmission for what I do. $5500 better be a flat out sled pulling transmission like powerstroke said.
