Overdrive in M715?

Swap to a divorced Dodge NP205, keep waiting for the low-range gears.

You have two easy choices for the overdrive...

Option 1.) Run a Ranger Overdrive torque splitter between the engine and trans and shorten your intermediate shaft (may have to move the t-case back) or swtich to a married mount 205, which would mean ditch the T-98 in favor of a SM465.

Option 2.) Run the Gear Vendors unit between the trans and t-case (probably have to move the divoced case back) or run the OD behind the t-case, eliminating OD in 4wd, doesn't sound like that big of a deal, but it might be nice if they ever make the 3:1 gears to be able to split that with the OD to a 2.25:1 for wheel speed stuff, of course with a 455 wheelspeed in high range won't be a problem.

Most importantly......PICS!!!

The gear vendors OD doesn't work at low speeds. I have one behind the t-case in an '85 Chevy, and it won't shift unless you're going >30 MPH, and even then there's a delay of about 3 seconds from when you pull the switch to when it actually shifts. The delay gets shorter the faster you go until you get to about 60+ where it's almost instantanious. Since he could mount it between the tranny and t-case, he could cut those speeds in half in low range, but it's not like a ranger or warn, where you can actually start out in OD. I'm not saying it won't work, just wanted to let you know what they're like before you sink a bunch of money into one.

I was going to do an NV4500 in my Chevy, but the Gear vendors OD was a lot cheaper, and I got 7 useable gears in 2WD. It has a couple disadvantages I mentioned though. Overall, I think it's great.
