Diesel Governor Recommendations

[AugustDiesel]

So my new 700r4 has a gas governor in it, which is throwing off my shifting points. Looking for a diesel governor to replace it with, any recommendations on brand/where to buy?

Thanks Robyn! I had seen that already just didn't know anything about Sonnax and their quality. But I'll give it a shot!

So, it seems to be a success. Prior to the diesel governor, it wouldn't shift from 1-2 until 26mph, 2-3 at 35mph, and 3-4 at 40mph. Now that the diesel governor is installed, it actually seems to shift earlier (doesn't seem to be a bad thing): 1-2 is at 10mph, 2-3 is at 20mph, but then 3-4 isn't until 45mph, and it seems to hold 4th really well vs before it wouldn't. Trans temp stayed right at 200 degrees, which is warm, but maybe not considering it's 95 degrees here in north Florida. No leaks anywhere, and it moves through the gears pretty well and fasts too.

So it seems, after a few test drives, I may not be out of the woods yet. While the shift points seem to be okay, the trans does not seem to want to down shift when getting on the throttle. Particularly in highway speeds, if I'm already in 4th, I can play with the pedal a bit to get it to downshift to 3rd, but even then, once I slam the pedal (for either passing other vehicles or climbing uphill) it just pops right back into 4th gear and bogs down. Any ideas on the cause of this?

Tis the nature of the beast. Without the control afforded to electronic transmissions, the older mechanical trans, needed that governor to keep the engine speed below the governed RPM (3,200 to 3,500 RPMs). The intent is to keep the RPMs as close to 2,000 as possible.

Takes a bit of getting used to as far as driving is concerned but the neither the 6.2 nor the 6.5 were ever envisioned as hot rods. Keep it calm and it will live a long and reliable life.
