Trans per year

My 97 PSD F350 eats a transmission per year. I have been using Jasper rebuilds because of the 3 year warranty. It is always overdrive I lose. I pull a 22' enclosed car trailer occasionally. I don't know what the heck is going on with this thing. This trans is under warranty again but do I need to look for another supplier or What? I do pull in OD out on the road. If in towns or somewhere it seems to shift alot I take it out of OD Am I doing something wrong or is Jasper not very good. By the way this is trans number 4.
Please advise.
Thanks

That sucks, I feel your pain. You driving habits sound OK, besides that's what the darn thing is made for (rant). It's a lousy design. (more rant).

I've heard both good and bad about jasper but after 4 trannies I would go somewhere else. It'll cost you tho even if you get your $$ back from jasper. A reliable trans can be $3K+. A bullet proof trans is over $5K.

Are they rebuilding the same trans or just swapping them out with another?

They are just swapping them out. There is a local shop and friend of mine that runs it. It is only down a day or so.
Another question. Do you think it will hurt anything to drive it around out of OD untill the repacement gets here? My wife only has a 6 mile drive to work and the truck runs fine out of OD.
My work is 28 miles so I don't think I want to do that.

How hot will it get?
Heat is the biggest killer of a trans.

what ^^^ MADVAN^^^ said. Do you have a trans temp gage. It's a good investment due to the weak link in an otherwise great power train. Heat kills!

Also, what torque converter are they giving you with the new trans or are they reusing the smae converter? Try to get a good one (triple disk) even if it's more $$.

No I don't have a Temp Gauge yet. But it sounds like a good investment. I also thought about a friend of mines truck with a chip that makes for a firmer shift as well as more power. Would that help?

Are you still running the stock 5/16 trans lines or have they been upgraded to 3/8? Extra cooler? Filter in return line?
Ford blamed my last trans failure on the 5/16 lines and my aux cooler being too small...not enuf flow and not getting rid of enuf heat. I can see the lines being a flow problem but the cooler was a 24,500 gvw cooler. Not sure the size of the one they put on in it's place but it's huge. Don't have a trans gauge on that truck yet...but then again I"m pulling everything with my 5 speed now. The day the ford tech rode with me trying to find the shift problem I spiked his labtop at 285* and lost 2nd gear.... Since it was the last day of warranty and a "selonid" didn't shift it was covered

i bought a 20k tranny cooler here at my local shop. Spent 49 bucks on it. Put a torque converter in it from auto zone for about 299 I think it was. that was three years ago, and I use this truck EVERY day, and 5 days a week its hauling 10k to 15k of weight behind it. If you run a good fluid, and get a big cooler, these things last a long time. and I always pull in od unless it starts hunting for a gear on its own.
