    4R100 trans or 4r70w F-150 driveshaft


    I was unfortunate to get the 2000-2001 mechanical diode trans in my 2001 harley F-150 truck so a few weeks back I did what you weren't supposed to do and it blew up, I had no idea

    so, since then I've pulled the trans 6 times and have been fighting torque converter issues and now a faulty trans, all within the past 4 weeks mind you

    so i'm looking for a replacement trans, or possible someone whom can rebuild it without bankrupting capitalone

    If I can't find another 4r100 in excellent condition then I'll just swap a 4r70w in it, but in order to do so I need the longer 4r70w driveshaft for an 01-03 f-150 supercrew

    let me know if you have either and pricing, you can call, txt, or email

    thanks for the reply, not too long after posting this I found a guy in mississippi that was selling the drivetrain out of a 2003 f-150, I got the engine and transmission with the driveshaft for $250 since he was doing a GM 350 swap in the truck and didn't need nor want the original pieces, I swapped it in that weekend and haven't had a problem with it since

    curious, what all do you have done to the 4r70w in the rebuild? And whats the status on the mark 8?

    I'm a supercoupe enthusiast/collector got 9 of them jewels and the mark8 fn10 chassis is very much similar to the tbird/cougar mn12 platform
