Tinny bit of "bucking"

[Galaxie]

I had a small load (2000 max) on the back of my truck a bit ago. When going up a hill about 50 or so, I wasnt into it enough to kick down but it was at a low rpm with good boost....I had a little bit of bucking.

Anyone have this? Normal? It went away when it kicked down.

I had that happen a couple times late last fall/early winter when my engine was cold. Shortly thereafter I had 4 injectors replaced and the computer reflashed for my really bad stiction problem. Never saw the problem again. I'm not sure why that cured it but it did. Hopefully that isn't the actual cure for it.

Thanks! No, this thing doesnt have stiction issues even unpluged at 17* outside. It only happend on a tune that locked the converter down low. The more I think about it, it was simply me easing way too slow into the throttle up hill, locked and not downshifting!

I should have thought before I posted! lol

Injector(s) or TC slipping. Check your trans fluid level

I agree, TC issue sounds like.

yeah, I have had the same thing happen, its the TC slipping from you getting in it at too low of an RPM and it not shifting right away. adjust right foot position and problem solved!

i have a similar issue in my truck but in second and third under accel with converter locked. my bucking is coming from the fact that i don't have traction bars and i have horible axle wrap. but it only bucks when towing not sure if maybe you are having any bit of the same thing happening to you.

Yup! That is what I have! Its not a power or a missing issue, just me on the right foot.

You can say it is your right foot all you want to, but it is not. You have a issue somewhere. Check your trans fluid.

Nope! I guess I didnt discribe it correcly. If you think of a bad running pig shuttering, that is not what this was doing. Just didnt shift out of 5th like it should have. its not slipping! I shouldnt have even posted this post. The transfluid is new has about 6k on it, red as my ELC

I do apprecate the help though!
