Default 700R or Gear Benders unit

I'm about ready to start the build up on a 75 and i would like to have an overdrive to offset the 12mpg I had before. Standard re-end with about 400hp and 370 torgue. I don't know anyone who has played with the overdrive unit so I was curious about the drawbacks other than the price. Thanksd in advance for ALL comments.

A well built 700-R is cheaper/easier.

I reaserched this and found the Gear Vendors install was going to require a good bit of cutting and fabricating, would give less overdrive (20% vs 30% for 700r4), and it was more expensive. The Gear Vendors has a reputation as a bullet proof unit, but I went with the 700r4 and have been very happy.

God bless, Sensei

I went with a 200-4r in my 76. Got it from Bowtie Overdrives. Bolted up using the original cross member...did it all in a weekend. Went from about 12 to 18-20 mpg on the Hwy. Would do it again. Love it.

Good luck.

For a shark, the 200 4r is the way to go...not an issue, much simpler and cheeper too....

I ditched a 700 tranny from my '72 shark, for a 200 4r I built for it here.....NET cost was about 300 bux....on the high side....

I rebuilt the tranny here in my garage, with little to NO experience, bet odds you can do it too....

What trans between the 700R4 and the 200R can handle more torque/HP?

..... It depends on how their built. Check the options on the BowTie Overdrives site for some info. I'm still planning to get the 200 4R, stage 2 for the mild built 355 in my 80.

The tranny core shop up the road wanted 60 bux for my CORE 200 4r.... then I have about 300-350 in parts....including a new converter lockup valve (don't miss that part on the rebuild, it's not in the kits, and don't ASK, damnit)....a new front ten vane pump, then a converter, and of course a complete soft parts kit, and a nice master/large Trans Go kit,..and NO OTHER, and a weekend in your garage with a nice 4x8x3/4 ply on some sawhorses, and READ the ATSG manual...and you got it dun....

unless you find major damage inside, which is doubtful, you maybe have another 100 buck hard part....maybe....

I did not....so far so good....

Has anyone on here actually used a Gear Vendors unit? I must admit that I really like the idea; even more than adding a 5 speed!
