I took the 727 tranny from my wife's 440 Sixpack powered 71 Challenger R/T in to have it gone through. The tranny guy is very well versed in Mopars. He said he had a later year 727 case he could use instead of the older(1969 I believe) case I took in. i just wanted to get some opinions as to if it's a good idea. The wife's Challenger is a street/strip car with much more street driving than strip passes. I'm planning on using a Bouchillon kickdown linkage if that matters.

Its the later valve body that is what he is talking about....parts from the later valve body can be used to help with shifting....
Its been years ..but I do remember reading this and useing it in a build up..... I am sure more exp trans guys can explain what it is that is diff..
All know it something about the valve bodies...
He was able to determine it was an older, non partial throttle kickdown tranny just by looking at the side of the case where the linakge bolted to?

Trading a possibly numbers-matching transmission case from an R/T for another case when the original case isn't broken would seem to be going backwards.
The part-throttle kickdown conversion was described by E-berg in Mopar Action a few years ago, it is a minor change to the valve body IIRC. Also isn't it true that a 904 valve body could give up the PTK valve?
R.
I wasn't going to trade my case, (it's not original to the car) He was going to charge me $50 bucks extra to use his PTK case and give me my bare case back.
Thanks.

Once again, there is no "PTK case", it's all in the valve body.

So will the PTK specific valve body fit in all year 727 cases?

find this mag back issue
http://www.moparaction.com/Next/history/oct1989.html
I found that earlier tonight. I also read that A&A transmission supposedly has a PTK conversion kit?, what that would be I'll find out tomorrow.

For what it's worth. I feel the partial throttle is important in a slant six auto or a stock 318 with a 12 in convertor. This upgrade with a 440 in front of it is just to say you have it. Big blocks accelerate just fine at partial throttle in high gear.

The thought in my head is the same as others here , it's a function of the VB , not the case .
