Every now and then when my truck up shifts into OD or out of OD it'll vibrate the whole truck idk what's going on but it started doing it after I put my 33" tires on

 

torque converter shutter,,,it's like a bad girlfreind, it's going out on you.

 

Mines been Doin that for 80k I just feather the gas and it stops just gotta baby it. Not really in the budget to fix right now for me.

 

Changing the transmission fluid can be a solution to this. From Wiki:

"A 20,000+ GVW cooler is highly recommended for all vehicles. Breakdown of the transmission fluid often results in "converter shudder" (feels like driving over rumble strips) where converter tries to maintain a steady slip rate during lock-up, but alternates between slipping and grabbing. Frequent fluid changes, especially when used for towing, are the single best method to prevent shudder. Shudder occurs because the torque converter never fully enters "lock-up", and ends up bouncing in and out of lock-up to slip. This causes the engine to flare up and then down again as the clutch cannot hold back the power of the engine."

 

Try Trans-X..... It has fixed man of my older AOD...Over drive shudders...

 

Yes it does it bad and sometimes I'll be running 1800 rpms at 40 and when it finally drops to 1300 I get some huge shakes kinda like I drove in a ****ed up road

 

Check engine light isnt on or flashing is it?

 

Mine started acting the same way at around 120000, changed the tranny fluid and filter and the hard OD shift went away.

 

This stuff work's very well for your problem. It is a crutch but it will take the shudder away. Most parts stores carry it.
