Hanging Transmission Mount Empty Hanging Transmission Mount

I'm working on installing a GearVendors unit and I have an A108 with a hanging 727 mount (see picture):

Hanging Transmission Mount Img_8510

Does anyone know if the bolts are threaded into weld nuts inside the crossmember?  I was thinking of unscrewing those bolts and re-screwing them through holes in a piece of angle iron flat against the mount.  Wanted to make sure I wouldn't muck anything up -- my suspicion was that the bracket is welded to the crossmember, but if that were really the case, I'm not sure what the bolts would be for.

the tranny is correct for the a100, the area on the bottom of the tranny
with 2 holes are in the casting of the tranny, the the tranny mount on the frame holding your tranny is welded to the frame. The dogbone on top of the tranny that has the bushing in it could be in the casting or bolted on, Idon't know why ?? i have both trannys i hope this helps,

I was referring to the tranny mount on the frame holding the tranny.  It has 4 bolts (you can only see one in the picture I pointed to arrow with):

There is another bolt above it and the another two bolts on the other side of the mount.

If it is in fact welded, why the bolts, just so it's stronger?  Will I be able to unbolt those and re-bolt them back in?

If it's bolted there is no way they also welded it.
i apologize for the bad info.

No problem. I assume it must have weld nuts inside the crossmember then, because otherwise it wouldn't have enough depth to thread into. Is that a reasonable assumption?

I was able to build a mount using angle iron and a trunk mount from Imperial Services, and hang it off those existing 4 bolt holes.  I used new 1/4" longer bolts to make up for the 3/16" angle iron I used.  I'll try and take some pictures this week.

Haha, Steve told me it would take a day or two. I bugged him every few days and it ended up taking 2 weeks from the day I ordered it until it shipped on his end, but it did arrive.

Would like to see pictures when you get the Gear Vendors installed. Also when you get a chance to drive it would like to know what RPM you will be turning at 65 MPH. What rear gears and tire size do you have?

Thanks...

I recently posted "GearVendors install" in this forum.  Take a look there for more pictures.

I have a 3.55 rear-end.  The van originally had a 3.91, but I had changed it out a few years ago for better freeway performance.  Tires are 215 75 R15.

You can use this website to run the numbers:
https://www.reillymotorsports.com/speed-tire-rpm-calculator.html

I can verify from watching my tach while driving that those are pretty accurate.

With my setup, 65MPH without overdrive is 2820RPM.  With overdrive, for the same RPM, you're running 83.8MPH, and at 65MPH, you're at 2200RPM.

Said another way, I used to drive 55-60MPH, which is 2385-2500RPM and a loud engine.  I now run between 65MPH-70MPH, which is 2200RPM - 2370RPM.  So 70MPH is lower RPMs/quieter now than I had at 55MPH was before.  When I drop out of overdrive at 70MPH, I'm around 3000RPM.

Thanks for the information !!! Sounds like your happy with it, besides quieter probably better gas mileage and runs cooler?

Very happy.  One of the best investments I've ever made (time and money) on my van.

The reduced noise is really nice, because now I can actually talk to and hear the passenger on high speed roads and freeways.

It does run noticeably cooler at high speeds.  I honestly don't pay that much attention to gas mileage, but it's presumably better.

Very cool.

I can't wait to see the pictures of the completed installation.
