Maybe I should have titled this thread "Help!!". Doesn't anyone have some wisdom to share?

Admin will have to move my vote of 3 sets to 4 sets. Guess I got trigger happy? Just put the 4th set in recently at 360,000 in the '95 6.5L. Should have done it sooner as this last set had 130,000 miles on them, but they go away so slow you kindof go to sleep. Sure makes a big...

Ok boys and girls, what would you do next? We took a gas 5.7L suburban, bought all new diesel wire harnesses ('99 vintage), flashed a '99 program in pcm, and stuffed a 6.5L in it. See signature for details. Current status; starts, runs drives, but has a few issues; 1. Wait to start...

Two VW's (1998 and 2002) and one Buick LeSabre (1981) for me. Sad to say, but since I couldn't vote twice for VW, the Buick counted equally, ironically 8 cylinders equal 8 cylinders, eh? Lol. p.s. I think previous pickups should count b4 tractors, but if u were counting garden tractors...

Thanks to Jim for sharing another page from the 6.5L Technical Reference Library!!! LOL!!

Merry Christmas All!! I can't top a clip from the classic Christmas Story!! I'm still laughing....

I love black, but could easily own a red ride next time. The '02 Jetta we used to have was very red, sometimes referred to as "arrest-me red". Oh that was a very good color. Ok with Pewter and Burgandy I guess. I'm not a fan of the blue, grey, white or green. But only puke on the...

I must say fella's... this is all I've learned from this thread thus far; 1. ATT guys are stand-up, they gave the fella a refund! 2. We still don't know what's wrong with subject vehicle, I'm pretty sure something isn't right, we just haven't figured it out yet. I'm sure we are all...

I guess if you want it done right, sometimes you have to do it yourself. Now the speedo and anti-lock brakes are sorted out. Still don't have cruise or tcc lockup. Hopefully we can sort that out this weekend. I'm excited to get another set of wheels on the road.

Here is the diagram/instructions, take a look at note A and B...

Based on the photos and a short discussion with GV's today... I suspect a GV installation wiring problem. Apparently, the stock vssb is only used to make the 4L80E work. Pin #15 has to be removed from the stock vssb and connected to the GV vssb. Also, if you have anti-lock brakes, pin #10...

Well, I thought the GV switched from one vssb to the other. I also see we are off by a couple divide ratios, perhaps we used a different number for tire revs per mile way back when we started this deal. My vssb is set to 25.297 rather than 24.750 as I expected. Not really significant. But...

I reviewed post #8 again as I obviously missed something. I'm still confused how the info I have has one less than twice as many calibration options. But I do see alot of the options that are inverted/opposite as your info shows buddy. As for the gear vendor? The GV is behind the transfer...

Both methods come up with the same result for the right hand seven spots. But what about the left hand seven spots when I use your method buddy? The method you posted appears to have 1/2 as many choices? I used 30.47 in diameter, 95.724 in circumference or 661.9 revs/mile for my 245-75-16...

I'll work on that. How the heck do I attach a pdf file or jpg file?

VSSB, ECM (PCM), cluster and tranny came from '96 3/4 ton 4wd ext cab short box 6.5L with 4L80E. Engine harnes, dash harness, tranny/transfer harnesses were all purchased new. Dash harness was actuall for an auto 4wd and we had to convert to push button 4wd. Four wheel drive shift control...

Update... 1. We calibrated the "main" vssb using the 6.2 6.5 Diesel Page Volume I or II. I'm fairly certain this info is good as we used this to calibrate my nephew's '99 1 ton dually and it was perfect the first time. Not to say we couldn't make a mistake, but not likely one due to bad...

Now that did make me laugh! But I'm still hoping someone has a clue!? Mileage really sucks cause you can't get into road gear when the ecm thinks you are only going 40 mph when you are really going 80 mph!! Let's see, if I could get to 55 mph (110 mph actual) you think she'd shift into...
