I've already done the Dual feed with the transgo kit, before the overhaul, where you have to drill the case.
Now that I'm doing the overhaul C K also has a dual feed where you have to remove a seal or seals.
My question is; do I do both where I remove a seal or do I leave it as is with the transgo kit and not worry about the seal?

 

Since you modified the passages under the valve body, you need to leave that as-is and do NOT do CK's internal mods. Re-install all the seals and the stock center support bolts.

Otherwise, you'd need to get a new case that hasn't been modified or re-build the wall that was drilled out. Doing both modifications might lead to a situation where reverse and third are engaged at the same time.

 

Very good explanation! Thanks for your help..

 

I’m just finishing up CK’s street-strip build, and they are now using a valve body/spacer plate mod to do the dual feed. Cris told me not/not to do the oil ring delete/oil feed plug mod per his manual - at least for this kit.

 

ok cool. I'll just leave the transgo kit as is..thanks
