    Mark, you and I have spoken before in years past, you've been a huge help before and I was hoping to bug you about a project I'm working on. I've built several very high HP engines (1400+ hp triple turbo 6.0's) and a common issue is controlling the 5r110, so a lot of guys swap to a 4r100. I'm looking at running a transmission controller that can run 4r70w and AODe transmissions. My question is, do you know if it would be possible to "re-pin" or change the plug for a 4r70w and wire it to the 4r100? I know it's an oddball question, it's for a racing application, not the run of the mill street stuff...but I haven't found anyone who is familiar enough with the transmissions to tell me if electronically/mechanically/hydraulically this is possible. My email is [email protected], if you have any time at all I'd be very appreciative of any help you could offer. Thanks!!

    thank you for the information. I was not sure if it was a fit. So many people kept saying it could have different tail shaft , number of starter bolts and cross member mount.?

    Thank you for the kind thoughts. The next 9-12 hours are going to be interesting. The eye is heading up the west coast and I'm on the east coast. But this thing is so massive that we will be right in the middle of it.

    Please explain what you want to understand. I created many of the tunes for Ford. That was my job there for most of the 19 years I was there.

    I have enjoyed your posts for several years. I hope you and yours are safe as Irma passes. I have a 2002 F350 7.3 4r100, Greg Evans/Dieselsite design. 380 hp engine up grades. I have the Minotaur PHP tuning system and have been having the dickens of a time trying to get the shifts right. Would you help me to understand the shift hierarchy? And maybe some definitions of terms? I know where I want to make shifts, just trying to let the computer know. Thanks

    Thank you for the reps and for providing insight to the group. I'm amazed at how hard headed some can be.

    code 33 took egr off and cleaned and replaced gasket,with applied vacum I get continuity,late shift 3500 to 4000 rpm to 2nd? or 3rd unless I let up at 2500 and It will shift hunts between 3rd and forth,od on /off seems to make no difference.If I put my foot in throttle neutrals out high rpm no gear or slippage? Put foot on brake will turn tires.Pulled psom today looked good .I found brake light upper roof mount burnt out socket replaced same.Blown 25 amp fuse for trailer replaced and did not blow again. Thanks Mark
