I've had my SmartyJr for about 3 weeks now and currently on the 100hp setting. My normal driving style is pretty easy going usually but sometimes I do like to get on it pretty hard when I pass on the highway. The last 2 or 3 times I've noticed not really a noise but a vibration like I'm on the 'wake up' grooves on the side of the hiway. This is only when I'm into it pretty good at 65-85mph. As soon as I ease up it stops. My first thought is that it feels like the splines are stripping between the tranny and driveshaft but I think that would put me on the side of the road the first time that happened.
Any ideas?

Get a Valve Body, that might help the TQ from chattering tell you get a better one

OR Mega Cab

I have experienced tha exact same thing on #3. I just changed to setting #1, and will experiment with it for a couple tanks before trying setting #2. Thanks for asking the question, I too was wondering what that vibration was.

Thanks for the info!

if you get a valve body, get a converter too.

then get a flex plate

Ever heard a bad U-joint.

if you get a converter get new shafts especially input.


Seriously though I'd just do a valve body, stock TC should hold.
