Second gear vibration

OP, one of your posts gave me the impression that they were doing TSB 0249-12, but that they did it bit by bit. Is that the case? Did they also to the dampener in the steering wheel, or just springs and the trans/transfer case mount?

Either way, glad to hear you got things worked out. After I get the driveline TSB done, I'm going to talk to them about the springs (a basic topper and 4 or 5 sheets of 1/2" plywood will bottom the truck). They may give me hassle since I have airbags - I may have to buy a set of bumpstocks, for back to stock for a while, get the TSB, then reverse it all. Lol.

 

The order of TSB was as follows:

1st appt. top of the "SEALED" tranns fluid...1/2 to 3/4 qt low with only 3k miles (no difference in ride)
This blows my mind!!! Why would they sell you something you could not maintain yourself...oh wait I know, so you have to bring it back to them and get bent over for service!!!!

2nd appt. trans / transfer case mount and steering wheel dampner
(this did make a difference with smoother highway ride...not feeling the ripples in the highway as much)

3rd appt. changed rear springs...after having a chance to drive it a while I'm more disappointed now than ever. Not only is the vibration still there, it rides like SHIT. I bought a Tacoma because I believed in Toyota. I dropped 30k on a truck believing I would be (for the most part) worry free for 250k miles. Instead I have a truck with 5k miles on it and I'm liking it less and less every time I drive it!!!! That SUCKS!!!!!!!

Sorry guys, gotta get it off my chest.

 

That sucks to hear. OK, after I get the driveshaft TSB done, I'll report back and let you know if that made any difference in the 1-2 shift issue/vibration. Maybe that'll be the ticket.

 

OK, back from the dealer with the driveshaft TSB done. I still get the "sproinging" sensation when I release the brakes at a stop and still get a vibration on the 1-2 shift, though it's not as bad now. This was with Ride-Rite airbags set at 5psi and then with 24/22 psi later.

BAH. I'm out of ideas.
