Pictures of fabbed up tranny crossmembers please!!

Hey,

I'm in the middle of swapping the drivetrain on my 41. I'm putting in a hot little Chevy 292, T5 and open drive rear axle. I've got the engine/tranny in place and leveled. Had to cut 8" out of the stock tranny crossmember to get the tranny where it needs to be. These chevies had the box type frame and the tranny cm is the same style. So, I need some inspiration and ideas on what to do for mounting the tranny. I've done some searching on the HAMB and in the tech archives and found a couple of posts but nothing that can help me yet. So,show me what you got...lets see some of what you guys have done/fabricated to re-mount your tranny!!

Thanks
Paul

 

This was for a radiator, but the process is the same. The retangular tubing in the front is for marking the cutlines. Then transfer the lines around the tube with a square. Cut then weld.



The cheap ass piece of crap motor mount tube in the rear of the picture got replaced also. It wasn't even welded...

 

Here's the 700R mount for my '46 Olds 76. 1/4" x 4" plate that steps up around 4". Nothing hangs below chassis. Secured with 4 x bolts, trim plate to suit x-member profile. Inside of rail is reinforced with 1" angle iron. I had to grind a radius on rear to allow it to fit snugly into corner of rail. Once welded it will be secure. Centre X-member doubles as a tailshaft safety loop. Mock up your mount first to ensure that the tailshaft does not foul, no room for error in mine with a 3" diameter tube. I used a piece of timber in lieu of a shaft for clearance.
No need to trim my x-member legs on mine as per 47 Ford installation, not sure about a Chev though.

 

Here's mine.

 

This is the mount we fabricated for the 5 speed in the '54 Wagon. HRP

Good stuff guys and thanks for the pictures. ANyone else out there got pictures of tranny mounts, especially if it was done in a similar vintage chevy!

 

My transmission mount is in a highly modified 42-48 ford frame - But I cut down a s-10 tube style t-5 crossmember -

Here's the crossmember

Here it is with the transmission sitting on it - it has 2 3/4 " nuts welded inside the mount , very strong - and 2 3/8" bolts to prevent any chance of rotation -

Here is a shot of it ( upside down ) with the upper brace elded to the frame -

Here is a front view -
I nkow it's not in a similar year chevy - but maybe you can get some ideas- It was all scrap and junkyard parts -Well T did have to buy the 3/4" nuts- I had the bolts and 3/8 bolts!

 

Thanks, thats a pretty neat idea!

 

Simple but effective. 1-1/2 x 2-1/2 rectangular tubing bolted to the bottom flange of the box frame on my 50 Chevy Sedan delivery.

 

Thanks lobucrod. I like how you used 2 bolts on diagonal intead of 4 bolts each end. This is probably what I'll end up doing or something very similar.

 

When we did the V-8/auto swap into my nephews 51 Chevrolet Business Coupe, we used the Chassis Engineering mounts. The motor mounts are fine, but the trans mount is strictly a weld-in affair. If the trans needed to be pulled, the engine would also have to come out, and that was'nt going to work for us. So, we cut the center out of the stock cross member, and used a modified MOPAR trans crossmember drop-out. Shortened it so it only uses one bolt/nut/washers for each side, and welded a plate towards the rear for the trans mount cushion, and it work fine. I'm guessing the late 40's frames are similar is design, so the same thing might work for you. Butch/56sedandelivery.

 

a trans mount is one of the easier pieces to fab up.. here's a couple of pictures of mine.. i cut out a section of the original cross member, welded on a piece of flat stock up against the section i just cut off and left about an inch on each side, drilled two holes to be able to mount the center section back in. i then cut another piece to match the piece i welded to the cut cross member, drilled a couple of holes and bolted it to the welded piece. i set the trans where it needed to be, cut a section out of square tubing i had laying around to fit between the flat stock that is now bolted in. welded it to the bolted in piece and now i have a removable trans mount/cross member...

 

Search a thread called brackets... Seriously it's on here

I fabricated mine from an old trailer hitch bar that was salvaged from an GMC P/U truck.In was a nice round tube with just the right drop. All I had to do was weld on a couple of mounting plates to the ends and a bracket for the actual transmission mount.

 

gsport,
I pretty much have the same situation as you had. I have to do something with the cut crossmember anyway. This will test my novice welding skills too! lol thanks

Deto, I'll check out that post!!

Moose, That looks sweet. Looks likt the Chassis Engineering mount I used on my 37 Nash years ago.

Thanks Guys,
Paul

 

Here is mine.
