Daystar KJ01007BK transmission mount for standard 4.0 liter transmission

A factory replacement rubber mount would have been a lot cheaper. However, it would also be a cheaper quality mount. By using the same mount on previous installations, I had no intention of skimping on anything that important. Considering that this also fits the stock 4.0 liter gearbox and there are many more of these than 2.5, it would be less confusing for future buyers if this fact was stated in the title or description.

Pros
  • Absolutely brilliant!
Cons
  • Vulgarity

On 1999 XJ 4L with automatic transmission

To fit 99XJ 4L with automatic transmission and offset pattern. The photos show this mount compared to the standard mount. In the picture above you can see the location of the screws and the Daystar expands even further, creating more metal around the hole. Side by side you can see a slight difference in height. I find it a bit quieter than the stock unit, but that could be due to damage. It went in easily. Overall it goes well with Brown Dog motor mounts. As the Daystar tech put it, the…

Pros
  • One year trial period
Cons
  • Minor repair

But overall happy with the product

Much stronger than the factory product. Stiffness coupled with new engine mounts really smoothed out shifting. Stiffness coupled with a slightly higher than factory specification would increase transmission vibration and noise when raised and while this was already a minor issue I definitely should have gotten an answer after adding this or alternatively the T- dropped body. Installation required moving the cross member 1/2-1/4 inch to the left to align the screw holes. I'm not sure if this…

Pros
  • Excellent overall performance
Cons
  • Poorly thought out

Unreliable manual mount

It says it will fit all cars from 84-96 or so, I have a 1990 XJ with 4.0 and manual transmission. It was the only polygonal mount appropriate to the style. It fits snugly and lowers the gearbox as it is thicker than the stock bracket. I had to dig through my spare bolts to find a waffle nut because the bracket gets in the way of the stem, but it bolts on. One of the 4 bolts holding the crossbar to the bracket came loose from the threads and I think I had to force tighten the nut, basically…

Pros
  • Heavy duty construction
Cons
  • Requires socket

He probably weighs over 5 pounds and is very stiff. The way poly material.

You won't realize how powerful this mount is until you get your hands on it. He probably weighs over 5 pounds and is very stiff. The way the polymer material is attached to the metal plates is really reliable. This bracket fits my 1989 Cherokee 6cyl/auto/4x4 perfectly. It is not listed here for the 6 cylinder engine, but it is the correct part. Once installed, the gearbox appears to be more tightly coupled. A little more vibration is transmitted to the cabin, but that suits me. I like the sense

Pros
  • Certified
Cons
  • Useless Features

Jeep XJ AW4 1996 version. TO UPDATE!

I installed this on my 1996 Jeep Cherokee with the AW4 automatic transmission. Fits almost perfectly. It fits perfectly where it needs to BUT the interfaces between the gearbox and the cross member are perfectly parallel. This vehicle's engine and transmission are of course slightly tilted, which means the 'part' of this transmission interface mount needs to be tilted as well. It's nothing that leaves a gap between the gearbox and this mount. I don't know if that will be a problem for me or…

Pros
  • Quality finish
Cons
  • Damaged

Daystar Poly Trans Mount - Great Upgrade

I installed this particular transmission mount on a '94 Jeep XJ Cherokee with a 4.0L engine and AX-15 5 speed manual transmission, having already used Energy Suspension had poly engine mounts installed. A complete "poly modernization" of the powertrain and transmission has significantly changed the way my Jeep shifts, downshifts and revs when the throttle is pushed. With a manual gearbox, the increase in vibration is minimal and hardly noticeable at engine speeds above 700 rpm. There's a slight

Pros
  • Heavy Duty Finish
Cons
  • Seller Communication
