Strange Torque Converter ???

Hey,
I was just eyeballing it off the hood to sky line and its not mountain hills but great lakes hills. The hills that are only a 30-50 yards long but climb rather fast out of a little valleys area. I was probably high in saying 35% but 20-25% is probably closer.

Thanks for the reassurance in saying this situation sound normal. The only thing that is still holding me up is that the truck barely gains 1 mph going down the hill nor gain anything in RPMS. At least thats what the tac and speedo shows.

Would there be anyway to use the programer to test the tranny for problems. Like changing a shift point or luck-up point?

Thanks

Ah, NOW I see. Buzz, I think your "hills" are too short to mean anything. And, I don't really know how you can test for much using the Gryphon. The only thing I know you can test is to see if the ISS = OSS in 3rd gear with the TC locked up. If they don't match in this condition, you have some "slippage", which would not be a good thing.

I imagine your TC was locking back up as you neared the bottom of those tiny hills and you started feeding the gas back in.

I thought you were talking about REAL hills (ones many miles long)! Not "bumps".

Jack, what's that last part supposed to mean? I literally live in "The Hill Country" of Texas so I think you should put your pedal where your mouth is and give our little "bumps" a try. I was wondering what kind of terrain so I topo'd it and saw a few areas that bore resembled to some tx hills over here. Are you sure your not thinking of mountains?

Buzz, you can try raising the lock points to see if that helps.

I used to live and drive through the hill country of West Texas my man. I've clocked many miles between Del Rio and San Antonio, as well as west out of Del Rio and north out of San Antonio. It doesn't qualify as a "hill" unless you see semi's down in low gear crawling along at 25-30 mph.

Haha hate to see what you call a mountain.
BTW Jack, your gonna be cited for indecent exposure if you keep that up...says batman. (he is looking kinda ticked so he's probably serious)

Best way to gauge grade percentages is if you're on a 12% grade then you'll drop 12ft every 100ft.
