Got the overdrive in with a little machine work to make the u-bolts fit, everything is running smoothly.
The biggest question I now have is about the operation of the Gear Vendors unit. I have a toggle switch that is marked Autodrive and Manual. I understand what the Autodrive is, the computer handles that.
But at what speed does the GV kick in?
Also, I noticed a marked reduction in engine braking on the freeway, is this the overdrive operating?
When I pull away from a stop with Manual mode on and the switch activated, am I to assume that I'm in 1st over?
I can't seem to find operating instruction for this thing. All I know is that when I flipped the manual switch on or off when rolling, I could feel the overdrive klunk in or out.
I drove on the freeway and found that my speedometer is about 10mph fast, it was reading 55 but I was doing a little over 66 according to my stopwatch. If the rpms are to be believed from the stock tach (it's bouncing all over the place), it shows me pulling about 2200 rpm at 66 mph. I did the math and I should be seeing a little over 1800 rpms with in overdrive, not 2200 rpms. I'm wondering if the tach is waaaaay off too.
Is this result consistent with the overdrive operating?
I have 3.55 gears in the rear end. According to their chart, I should be at 2.76 when in overdrive.
I also should mention that I have 33" tall tires.
Sorry for the long post but I want to make sure this thing is working after all the hard effort I put into getting this thing installed.
