Gettin' the dually back.

After a major transmission replacement, the driveway will be full once again.



I posted a week or two ago about buying a new Banks billet torque converter for my '99 F350, 7.3 PS, with 4R100 transmission.



Last Wednesday, I pulled the transmission loose, and slid it back, to change the torque converter. It had been diagnosed as defective. I took out the old one and shook it, just because, and it sounded like loose silverware and marbles inside. Not good.



Decided to pull the transmission pan. Found the magnet 1/4in thick with debris, and some thin metal slivers mixed in. Instead of going any further, (I don't do automatic transmissions) I took the whole mess to my dealer, where a long time friend and transmission mechanic works.



The overdrive, or what was left of it, appeared to be the culprit, I chose a new replacement transmission instead of a rebuild. Not much more cost, but much better warranty. I don't know why the overdrive went, unless I was at fault somehow. I'm looking forward to driving it again, and not at all disappointed in the transmission failure. The truck has 85,000 miles on it, and has been tortured pulling farm and grading equipment, and horse trailers, all it's life. Less than 10% of the mileage on it was without a trailer attached, I don't think that's too bad.



In addition to the new Banks, I have the Hypertech Stage III programmer. I'm looking forward to seeing how it'll pull the John Deere skid loader and old Ford 3930 tractor now!

upgrade to the BTS tranny... guaranteed for 2 years, up to 600HP...

Believe it or not, I read about that trans, but went with the stock transmission with a few upgrades, including lower first, bigger sump pan, and a Banks Torque converter. I still get the factory 3 year 36K mile warranty. I was told the failure was a fluke, and shouldn't experience it again, especially with my upgrades geared toward longevity. Spdloader

kewl...

you also might look into adding a sonnax valve and tricumulator springs (mini shift kit, very cheap, and effective, about $50) and changing over to mobil 1 synthetic tranny fluid... I love mine, it adds a little pressure to the shift valve, the shifts are quicker and a little harder, but not harsh...

Thanks, should the trans have a few miles on it before switching over to Synthetic? Spdloader

transmission

I did mine at 20K, I havent heard anything about waiting for any period, I would think, the sooner the better, less heat, less damage, etc...

disappointed
