As advertised, functional and works as it should.Item looks like it was haphazardly wiped with a rag and parts thrown together. Make sure to pick out all the packed dirt and grease because it comes with plenty. The snap ring foe the cover was a nice rusty one so I reused my old one.

I would strongly suggest you use your old servo cap this is a great assembly the cap just dosent work the new cap is smooth as the old cap has a ridge for the snap ring to sit into I didn’t catch it made it not even two minutes down the road and it shot itself out luckily the snap ring stayed pressed up against the heat shield also had to reuse factory snap ring as I did not receive a new one other than that I recommend this upgrade

1988 700R4 installed in a Jeep Cherokee with a 3.4. Works perfect! Nice firm shifts. I checked the travel with a dial indicator and the supplied pin worked in my case but always check it. This was a used transmission and I just wanted to do what I could to it for a good solid shift and this seems to be working as advertised!

I do not recommend this product to anyone. The servo pin, 4th gear piston, and housing had excessive wear and dirt all in it. I pulled it apart and used my original servo pin, 4th gear piston, and housing. It Looked like they pulled it straight out of a used trans that had water/mud sitting in it then slapped the corvette servo pack in it and painted the cap black.

Worked with my 2001 Chevy Silverado 1500 4x4. It did make the shifts a bit more firm, and seems to make throttle response a touch more crispy. Took 30 mins to swap out the servo, and I used a floor jack and a creeper.

Used it on my 2004 Chevy Silverado v8 4.8 with the 4L60 transmission. Shifts firm & fast feels like a brand new truck. I’d say it took longer to lift the truck up than installing the part lol.

Came in the mail earlier than what Amazon said but normal time if you ask me. 2-3 days. Swapped it out and back in business. Fit perfectly in my 2000 Silverado. 4th gear piston was in backwards when I took it out of the box so I flipped it over before I installed. All is good.
