Took care of the engine light and shifting problem Review: Great quality - These are excellent, and super easy to install, better than paying a transmission shop to do a hour job. It does come with a one extra so make sure you get it in correctly. The tool is easy to use too. I would recommend using fluid when installing them into the plunger. It goes more smoothly. And make sure you use the tool, the boot part to seal the rubber piece in. You can use an eraser on a pencil to make sure it doesn’t move, and I used air to make sure it was sealed as well. ## Features - 【Great Compatibility】Perfectly fits for GM Transmissions 6L45 6L50 6L80 6L90 6T70 (Gen 1) 6T75 (Gen 1), Works with F 124740-30K.

The seals to the shift solinoid wear out and allow trans fluid to slip by and not shift. Got these seals come with install tools. Not bad to install. Take your time. Shifts and drives like new. ## Frequently Bought Together - 124740-TL30 Pressure Switch Installation Tool Kit Works with F/124740-30K, Perfectly Fits for GM Transmissions 6L45 6L50 6L80 6L90 & 1st Gen 6T70 6T75 - 12474030K - 6L45 6L50 6L80 6L90 6T70 6T75, SONNAX PRESSURE SWITCH REBUILD KIT - GM Genuine Parts 24229593 Automatic Transmission Control Valve Body Cover Gasket --- ## 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.tn/products/287865265-124740-tl30-pressure-switch-installation-tool-kit-works-with-f](https://www.desertcart.tn/products/287865265-124740-tl30-pressure-switch-installation-tool-kit-works-with-f) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-17*
