Clarification regarding 69 Turbo 400 verients

[Mr70]

Frank repop the CW tag for cryin out loud!
I'll buy ya a Saasage wit.

Da saasage sounds good but the problem is I had a bunch of these tags made and I'm gonna die with em. The only 70 tags I've got are CYs.

Steve: what are your intentions with your car? If it's NOT gonna be a regular at the strip, I'd just get a THM400 from a reputable tranny shop and be done with it...it will last forever, and if you're wanting the look of the 6-bolt converter then buy one (don't they repo these?) and bolt it on. If you want to get really involved, B&M sells a governor weight kit that explains how to taylor the trannys shift points to your needs, but I wouldn't mess with it...

Certainly, any THM400 would be cheaper. I was just hoping
to find an original CX THM400 for the originality factor.

Can anyone verify for me if the front pump cover on the CX
or CY THM400's had eight bolts vs. six bolts on the standard
pump cover. I have two THM400's in my garage and one has
6 bolts and the other has 8 bolts. I have been told that
the CX and CY THM400's used 8 bolts and that is one way to
know it's a CX or CY. Did any other THM400's use the 8 bolt
pattern?

Any input?

Look at the chart in the link Belair posted above...if there are any dissimilar parts used between a CY/CX trans and a normal trans, that chart would show it.It also shows the part #s, so pull scribble down the part number and take a look at the chart...if you can't find the number on the chart, holler back, and I'll pull out the original Hydra-matic papers and take a look...

[nuch_ss396]

I just reviewed the chart. I'm not sure if the "cover
assembly conv. housing" on the chart refers to the pump
cover I was referencing. Any chance you can find out?

I can't remember exactly,but I think my CW TH400 (L78) uses 8 bolts.
