Just noticed this AM that the truck will not shift into OD like normal. All the other gears shift nice and quick at part throttle, but from 3 to OD I have to completely let off the gas...and then its like the converter unlocks is all it is. Once I step back on the gas (say at 50mph) the revs come up and I believe its in 3rd gear.

Every now and then it will shift into OD, but not quick like it normally does.

The trans fluid level is fine, the color is right, and there is no burned smell to it. I have a FTVB in the truck, so I am going to pull that and reinstall the stocker and see if that could be it.

It almost seems like a "throttle valve" problem (needs adjustment), but since these are electronically controlled transmissions, that isn't it.

Yesterday I did have it up to ~110 WOT in 3rd, but I let off the throttle before it shifted into OD. I wouldn't _think_ that would have hurt it. ???

Oh...and 9300 miles on the truck.

Thoughts?

 

Well I just finished reinstalling the stock VB and everything is fine (just what I figured).

This is the last time I buy a used driveline part. I went against my better judgement when I purchased it. I'm sure it was taken care of as well as any used part, but I had a FTVB in my '99 L for a long time with no issues, and I've installed new FTVB's in other people's trucks... at least 4x and none of those have ever had issues.

I guess I'll just get a new one. I like the product.

 

Send it to me and I will fix it for you...

Or send it to me and I'll update it to the most current model and send it back. Actually, just shoot me an address at gregg@factorytech.net and I'll get you a new one out and you can send it back here.
