034Motorsport is proud to offer our Street Density Transmission Mount Upgrade for the B8/B8.5 Audi A4/S4/RS4 and A5/S5/RS5 & B9 Audi A4/S4 & Q5/SQ5! The factory Audi transmission mount assembly features a soft rubber damping medium, which allows for excessive transmission movement at increased power levels, and can break down over time. This movement can be observed as hesitation or lurching when accelerating, decelerating, and shifting.

This high durometer performance mount upgrade is designed to be a direct, drop-in replacement for the factory damping medium, and limit unwanted transmission movement. By reducing slop, this upgrade ensures that you're experiencing crisper shifts and a more connected driving experience. This upgrade may introduce some additional, perceivable increase in noise and vibration transfer into the cabin, especially on vehicles equipped with the Tiptronic transmission.

In addition, the factory transmission mount assembly components are not available separately from dealerships, and premature failure of this mount can result in having to buy the entire assembly. The Street Density Transmission Mount Upgrade from 034Motorsport lets you reuse the factory cast portion when replacing/upgrading the stock mount.

This mount was thoroughly tested by 034Motorsport, and independent Audi enthusiasts before release. Installation is very straightforward, and is completely reversible.

Features:
  • Manufactured from 65 Durometer Rubber
  • Designed to Upgrade Factory Transmission Mount Assembly
  • Engineered to Work in Conjunction with the 034Motorsport B8/B8.5 Transmission Mount Insert & B9 Audi Transmission Mount Insert
  • Further Reduces Transmission Movement During Shifting, Acceleration, and Deceleration
  • Improves Shifting Feel & Throttle Response
  • May Cause Some Increase in Noise & Vibration Transfer Inside Cabin, Especially on Tiptronic Cars
  • Straightforward, Fully-Reversible Installation!

Cat Approved
So I have several self warming pads, this is the first one all three cats like. The outer cover is similar to the fake rabbit fur blankets and that was a huge hit in my house, everyone kneaded it excessively. While the pad isn't thick it does generate some heat keeping my smallest cat warm. And even my fattest guy liked it. It is made well and I am already ordering a second.

Small cat (or dog) warming bed.

LOVE this warming cat bed!! With a tiled or cement floor, this is an ideal strategy to remind little pets that this is a warm spot for you to lay your head <3

Great.
Size: 27.6"L x 18.8"W x 0.5"Th, Color: Grey
My cats love these. Will choose these over and over again. I had to buy multiple so they could each have one. Does seem to help keep warmth in. It’s also easy to clean.

Warm, Comfy, and No Electricity Needed
Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey
This self-warming cat mat works well — it reflects body heat and stays noticeably warm without plugs or electricity. The surface is soft and cozy, and most cats seem to take to it quickly. It's lightweight, easy to clean, and fits well in beds, carriers, or on furniture. It’s a bit thin, so adding extra padding underneath may help. Also, it can slide on hard floors, so best used on carpet or fabric surfaces.

He loves it. I wish I had purchased the large instead of the medium, but it still fits him okay. If he stretches out, it won't, though. :) He's a big boy. I have it lying on a bed in the spare room, where he often is, looking out the window. It's soft and makes barely any noise. It doesn't slip on the bed. I might on the floor. With anything new that we buy him, we spray it lightly with catnip spray and he always takes right to it, as he did with this. It's warm under his body. He's happy, we're happy! :) I ordered the larger one. It got here today! I moved the smaller one to a window seat. I hate when the delivery guys add, was handed directly to homeowner, no it wasn't It was put in a package box outside, ringing the door bell is not the same as handing it directly to me! LOL
