4r70w

  1. V6 Tech
    Hey y'all! So my the 4R70W off my 97 V6 is giving up the ghost (shudder while accelerating, slips gears between 65/70mph). I followed the advice of others and got my hands on the improved 1998 4R70W while junkyard shopping. Now I know the 1997 transmission connector has to be re-pinned for...

    Hey guys. I have 1999 mustang GT that started its life as an automatic and was recently converted to a manual. The transmission used was a TR-3650 out of a 2003 Mach 1. Everything went pretty smooth however i cannot get my speedo to work at all. Its still the factory Auto ECU custom tuned for...

    Hello, First off, this could be the totally wrong place to post this, so Mods, feel free to move me if necessary. But anyway, I've recently been considering adding another Ford to the corral, most likely in the form of a 94-97 4.6L Thunderbird. I see them around from time to time going for cheap...

    I have a 1998 Ford Mustang GT 4.6liter, with the 4R70W transmission. My problem is an intermittent delay of up-shifting from gears 2-3. There are slight patterns that I have noticed, that can affect how this problem occurs, or doesn't: If I use VERY light gas peddle, literally just...

    I've seen a few threads about the problem I've had a few times these last months, so I just want to share my story/experience. I will not post a step-by-step guide on how to do this. I will not recommend this unless you are mechanically inclined or have someone who is with you to help. I've now...

    Anyone here have experience with on of these? I'm looking to buy one but not for my mustang... Another project I'm looking at is a 1999 f150 reg cab stepside. Looking to drop in a 5.0 DOHC crate motor and putting a 4r70w behind it. Engine and trans will fit. But I've been told I wont be able to...

    :waveyHello all, I have a 1998 Mustang GT 4.6 and am needing (as far as I know right now) to replace the transmission. It is the 4R70W automatic and I've looked around to see what my options were, I have seen information telling me conflicting stories. Can anyone tell me what year and model...

    I'm looking at doing a tranny swap in my 67 Mustang. I've got a 1970's 351W motor. I've found a 4R70W AOD from a 2003 V8 Mustang. Does anyone know if the bolt pattern matches a 351W for a direct bolt in fit???? I realize I'll have to add an electronic control module and some other minor...
