Default Unsolved issue!

I recently posted something about the front end of my truck hopping when the turbo spools. Feels like the front end is jumping. Someone mentioned that it might be a torque converter issue, but I got around to checking the fluid and it's a nice red color and smells fresh.

I took the truck for a spin and duplicated the problem. I watched the tach and didn't see any fluctuation, whatsoever, during the jumping, so I'm inclined to think that's not the problem. Any comment?

I'm thinking of replacing the front shocks, but I can't see how that could be the issue. I checked to see if the engine mounts might be causing the problem, but couldn't see much engine movement when she was revved up ... I'm at a loss!

I have KYB MonoMax shocks all round. I changed the front shocks to a shock with slightly different travel to match the 2" over stock springs I installed. KYB helped me out with the specs, but I'm starting to wonder if the stock specs might suffice. KYB couldn't get a shock that was perfect for the slight difference in the spring length, but, according to them, the shock they recommended is better than staying with stock. This is the reason I'm thinking about changing them out. The truck feels great and the shocks seem to be fine ... other than the bouncing feeling I'm getting and I really don't know that it is the shocks.

Okay, threw a P0720, which is the tranny speed sensor; could this be causing the issue, if it is tranny related?

Well now you'll start looking over the tranny and all sensors and wiring for sure...

Okay, replaced the sensor ($21.95 from the dealer) and the truck turned into an F250 ... gotcha, Dennis!

Just a tip for anyone who's going to tackle the job. It takes all of 20 seconds (if you're slow like me) to change the sensor, but, if you're a dumb *** like me, you'll spend another 20 minutes cleaning up the pint of tranny fluid off your driveway, once your done! So, get the new one ready to go in, before you remove the old ... might want to throw an oil drip pan under there too!

Hopefully, this will solve the issue ... I'll keep you all posted!
