Another transmission question shift

I have 3 bb transmissions that none are out of a Challenger, will i still be able to use them and use a floor shift? Car has a column shift but was thinking of going with an aftermarket floor shift? Is there a difference between the cases? Thanks for any info!

Any 727 will accept an aftermarket shifter because they mount on the pan rail or tailhousing. To use a factory floor shifter, the tailhousing has to have the two "bumps" on the bottom for the shifter bracket.

Thank you. Is that just an E body case? or did other cars use it?

Check out how to videos online on installing an aftermarket auto trans cable operated floor shifter and you will see how to mount it to the trans. Normally it's a bracket that mounts where the tail housing bolts to the trans and a second bracket mounted with the pan bolts.

Will do, thank you.

I converted my factory shifter to cable on my 68 Charger, work awesome.

Is there a kit to do it??

Not that I know of, I bought a B&M cable & brackets & linkage that goes on the trans, made the bracket at the shifter.

Thanks. I'll look into that!!
