My favorite. Pretty sure you BORROWED that from me. :happy175: I love that chart cuz it gives the case dimensions, the tailshaft dimensions, the mount dimension location and all.

Could be, lol. I used to have one that I saved from CK5. Then I had to clear out memory space on my phone and it ended up on a memory card somewhere. Then I probably saved the one that you posted, but then lost it when my phone got dropped. Then I got this phone a while ago. I just went and Googled "GM transmission lengths" so I could post a chart here and when I picked one to download, it asked if I wanted to download it again. So I went and looked in my photos and sure enough, I had already downloaded that one in the past, lol.

Basically, if I post an image and it's not one I took myself... I had probably just stole it from Google.

I have installed several lockup controllers from Bowler Performance transmissions. Thats all you would need electronic wise. Your driveshaft would need to be shortened as the 700r4 is about 2.5 inches longer. Also crossmember would have to be relocated.

The 2 I've done were as follows 700r4 out of a 84 Camaro I put a check ball on top of the lockup solenoid the check ball made the converter lock when you went into 3rd gear. Other one I used the 4th gear pressure switch to ground an iso relay and lockup the converter. @Matt69olds is better with transmissions than me. I hope he sees this and chimes in.

Hey, if they're posted on the internet, they're free for the taking. I'm sure I stole it from someone too.

700r4 bolts into the same place as a TH 350 and you don't have to shorten the driveshaft. The 700r4 and TH350 or the same length.
That's only true if the TH350 has a 9" tailshaft, which is somewhat rare. With the more common 12" tailshaft you will need to shorten the drive shaft and relocate the crossmember.

However, a 2004R is the exact same length as a TH350 with 12" tailshaft.

Here's another chart: https://www.monstertransmission.com...imensions-Measurements_b_84.html#.X_vKLdhKjmE

Uhhh Not So brutha. The Squarebody Th350 is the 9inch tailshaft Th350. Squarebody is what the 9in was made for and is common as hookers on Sunset and Vine in Hollywood. It's the 12in that is rare that most people don't even know exists and why they call the squarebody Th350 a long shaft, when it's actually the Intermediate shaft unit. The 12in was used in station wagons and some vans in the late 60's and early 70's. Passenger cars got the 6inch and is also very common.

Also, the 200 R4 is the same length as the Th350 with the 6in passenger car tailshaft, so the 200-R4 will swap into a Chevy Monte Carlo with a Th350 6in shaft, or Th200 Metric POS, or a 70's Chevy Nova, since passenger cars had the 6in output shaft, BUT, not the squarebody trucks that came with 9in tailshafts. The 700r4 WILL Swap into the Squarebody trucks that were OEM Th350.

The tail shaft for the one I have is a 9".
Which means is a Squarebody OEM transmission and will direct swap with a 700r4 and vice versa.

Sorry we we're using your thread to have this discussion. It's educational and on the bright side, it keeps your thread up on top so maybe someone will see it and need one of these. :waytogo:
