This was installed in a Caprice wagon with about 80k miles on the transmission. I installed them all at the same time, so I don't know how much of the improvement came from each of these parts. The shift improvement was noticeable to me, but definitely not harsh. My wife did not seem to notice or at least did not complain. So if you're looking for neck snapping shifts from your 4L60, you will need to do more than just these 3 parts. In vehicle installation for this and the 2nd super servo was not easy. I had to remove the trans crossmember and lower the transmission as far as it would go. I also pulled the passenger side cat. Clearance was still very tight and this was not an easy install. Installation in a transmission removed from the vehicle would have been pretty simple. Review: I bought this along with the Sonnax 2nd gear super hold kit. My 03 Silverado, 2nd gear was starting to slip, but 4th seemed fine. 1st thing I did was change fluid completely(wasn't too bad) and the filter with the AC Delco Dexron IV. This didn't help much. I figured I'd spend a bit more and see if these kits would work instead of a costly rebuild. They did, and the truck has a much quicker shift too. Wasn't a quick easy job, but well worth it. Hopefully it lasts a while. Machining quality is very good. These are high quality parts for sure. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BYG72M8 | | Brand | Sonnax | | Customer Reviews | 4.8 4.8 out of 5 stars (92) | | Item Weight | 50 Grams | | Manufacturer | Sonnax | | UPC | 696749965443 | ## Images ![Sonnax Super 4th Servo - Image 1](https://m.media-amazon.com/images/I/41e5LjMGPTL.jpg) ![Sonnax Super 4th Servo - Image 2](https://m.media-amazon.com/images/I/51RUfPAI9pL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***T on 3 March 2018* I ordered this kit with the Sonnax super hold 2nd servo and the Sonnax boost valve kit.

It works great, can't really tell a lot of difference in the shifting. I bought this because my overdrive suddenly stopped working, turned out to be my computer. I built my 4L60E with other sonnax upgrade parts, and am very happy with the way my trans shifts and performs. ## Frequently Bought Together - Sonnax Super 4th Servo - 4L60 4L60E 4L65E 4L70E Transmission 2nd Gear Super Hold Servo Kit Sonnax - Sonnax HD 2-3 Shift Valve --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/61652163-sonnax-super-4th-servo](https://www.desertcart.com.sa/products/61652163-sonnax-super-4th-servo) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-04-23*
