    Hey All,

    I've been lurking for a little while and have learned a ton on here.

    I purchased a 62 Travelall 2wd 266 not too long ago and the transmission would not shift to 3rd, also had bad slippage from 1st to 2nd if heavy on the throttle. I found a guy locally who was selling his Borg Warner trans and claimed it had been rebuilt and in good working condition. He also gave my his flexplate and torque converter.

    I took all the old out, replaced the rear main seal and sealed up the rear camshaft plate. I went to put the new flexplate in and it looks like I need a spacer to run it. It does not bump out like my original flexplate. I would throw back in the original flexplate and torque converter, however that flex plate was rubbing on the oil pan and part of the block (also seems like it should be shimmed out a little).
    I'm hoping someone can tell me what I need to do to run the new flexplate and torque converter. If not, then tell me how to run my old flexplate but correct the issue of rubbing against the block/oil pan.

    I have seen that IH used a spacer between flexplate and crankshaft on some models, but thought I read somewhere that it was for the 727 transmissions.

    I have attached some pictures for reference so y'all can see what I'm working with. The 2 flexplates and torque converters are vastly different. The "new" stuff is the blue torque converter and the black flexplate. You can see in the picture the one was rubbing the face of the flexplate pretty bad. 20190712_221523.jpg 20190712_221526.jpg 20190712_221532.jpg 20190712_221549.jpg 20190712_221611.jpg

    I'm tempted just to ditch the IH stuff all together and run a Chevy or Ford engine and get an overdrive trans, but part of me does want to keep it original. I actually enjoyed the little 266 and would love to see how it would do with a 4bbl carb on it.

    Thank you,
    Dylan

    You need a crankshaft adapter/spacer for either of the flexplates. All the B/W auto flexplates I've seen need them, as well as the Torqueflites. They're kinda rare as many get lost track of. I would try contacting the seller of the replacement transmission, he might have forgotten it. Also some IH vendors such as Coonrod's, IH Parts America, The Scout Connection, etc. may also be able to help.

    How thick is the spacer supposed to be ? Also, do you know the IHC code for this transmission ? Like # 13049 ? It would be on your Lineset ticket. That tells you what all the truck was ordered new with.is your truck a C-100,110 ?

    Thanks for the replies. I kind of figured I was missing something. Reached out to the guy I bought the tranny from and waiting to hear back.

    I'm assuming there are different thicknesses dependent upon what came from the factory so this may be a challenge. This thing has been worked on before and obviously wasn't put back together correctly when I bought it.

    I'll call around to some IH shops too. Thanks again

    There are more than one style converter and flex plates for that tranny

    Thanks guys. I have found a couple of the thicker ones for sale, I believe that is what I'll need for the shallower flexplate/torque converter combo.

    There's a few of us running the 700R behind the IH V8s. Being 2WD, you'll only need to modify one drive shaft. The OD makes a big difference going down the highway.
    Just in case this BW doesn't work out...
