As long as you keep the non-LU parts as an assembly i.e. shaft, clutch retainer, support and pump housing, you can use them. Pic below shows the difference in the supports.

The changes between lockup and non are as mentioned, the pump housing never required changes to move from non to lockup.

The only changes for the actual pump from early sixties to end of production, except the 48 was enlargement of pump passages and port timing changes.
The quieting ramps also changed location, style and length but that’s nothing to worry about on the high performance stuff.

On the lock up shaft is that third ball plugging the converter fill port? If so that would be a bad mistake to make to swap parts around.

I looked over the parts I have on the shelf and they look just like the picture. So I put a tag on the lockup part to keep me from using it by accident. The pump bodies appeared to be identical as did the pumps so all of that looks like it can be interchanged. I didn't even know that I had a lock up 727 sitting under the bench until I tore into it. It has been sitting back there for 10 years and I never took a close look at it. I think it came out of a 1978 Cordoba that I parted out years ago. I just pushed the trans under a bench and figured I'd look at it some day. It has a lot of nice looking parts inside so I've been going thru it trying to see what I can use. Looks like I can use most of it except for the input shaft, reaction shaft and valve body.

Yes, that's why I recommended keeping the like-year parts together.

I could be wrong but I don't think the pressure angle on the splines for the diesel front planetary are the same as 1970 and older which would include push button trans.

The diesel pinion carrier is modified by re-broaching the spline angle.

I pulled an older support off the shelf today and looked at it and it only has two passages with one blocked. So this much be another variation. I'm not sure what this support came off of but it is pre-71 since it has the smaller bearing surface for the narrow bushing hub.

That's what I thought. Not a bolt in.

We did all that the same way but did not dfo the park gear.
What would tgat have done for me?

My understanding is that it stops an oil leak as it's no longer needed to feed the governor.

Usually, plugging that hole is only done when using a roller bearing in the rear support; that, along with installing the front sealing ring on the park gear, helps retain the lube pressure that is lost through the rollers.

I decided to build a dolly for the 727 just to make it easier to move around. Went with a three wheel design since I didn't see any reason for the fourth wheel. Seems to work pretty well. A fully loaded 727 rolls around nice and easy on the 5 inch casters.

I've never had a great way to hold the pump housing while working on it so I went ahead and made a tool for the job.

That's nice holder. I put the pump on top of an empty paint can

I wanted to be able to clamp it in a vise so I could use a torque wrench on the bolts. I got tired of wrestling with it so I just made a holder. Should last me forever.
