I used it on a C3 vette TH400. It was a little tight on the shaft and I had to screw bolt in to have enough clearance between body and trans to put on shaft, gave it a hit with hammer to seat it, screwed it in about 1 and 1/2 turns, turned the bolt and like magic it pulled it out. Tool worked for me and it still looks good to go again if I needed it and it comes with seal. I would recommend. Review: Good seal removal and install tool. - This tool is perfect for a turbo 350 or 400 transmission selector shaft seal and will remove the old seal efficiently, and the new seal fits perfectly as installed with the driver in the kit. Be aware that a 700-R4 or M30/4L60E transmission has a longer selector shaft and this tool will not work for these transmissions, but the seal will do fine using a socket. ## Features - 【Removal and installation】: There is no need to remove the transmission disc, or in most cases, it is not even necessary to lower the gearbox. - 【High quality】 using high quality steel rubber, performance is guaranteed, long life. - 【Compatible with】Fits for gm200, 200C, 200-4R TURBO 350, 350C TURBO 400, 425, 475 gm700-R4 gm4L60 gmAllison - 540，includes Seal. - 【Easy to install】. In most cases, the gasket can be removed and inserted, so you don’t have to worry about removing the gearbox or lowering the gearbox. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | E-cowlboy | | Brand | E-cowlboy | | Item Weight | 9.9 ounces | | Product Dimensions | 3.35 x 2.36 x 1.34 inches | | Manufacturer Part Number | g350 | ## Images ![Replace for GM Shift Lever Seal Installer Remover Transmission Tool ，Turbo 400 350 300 700-R4 4L60 Includes Seal - Image 1](https://m.media-amazon.com/images/I/51KnXmvZ5AL.jpg) ![Replace for GM Shift Lever Seal Installer Remover Transmission Tool ，Turbo 400 350 300 700-R4 4L60 Includes Seal - Image 2](https://m.media-amazon.com/images/I/71Ia-TOrYCL.jpg) ![Replace for GM Shift Lever Seal Installer Remover Transmission Tool ，Turbo 400 350 300 700-R4 4L60 Includes Seal - Image 3](https://m.media-amazon.com/images/I/61-ul7drdHL.jpg) ![Replace for GM Shift Lever Seal Installer Remover Transmission Tool ，Turbo 400 350 300 700-R4 4L60 Includes Seal - Image 4](https://m.media-amazon.com/images/I/61tuBp9AlpL.jpg) ![Replace for GM Shift Lever Seal Installer Remover Transmission Tool ，Turbo 400 350 300 700-R4 4L60 Includes Seal - Image 5](https://m.media-amazon.com/images/I/61QlylfP5qL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great on TH400 *by P***E on November 7, 2025* Was a little sceptic but it worked.

Be aware that a 700-R4 or M30/4L60E transmission has a longer selector shaft and this tool will not work for these transmissions, but the seal will do fine using a socket. ### ⭐ Useless. Trust the other reviews. *by J***L on November 21, 2025* This tool is useless - and let me tell you why. The product listing specifies the tool is applicable to a th400, which I have. Important fact, the shaft that the tool must slip over is right at 0.495” (measured with a micrometer and probably spec’d by GM at 0.5” +/- .005” from the factory). More fun fact, this tool has an inner diameter of 0.48” (product listing says it is 0.5”). Now, it’s made in China, so 0.02” tolerance is probably acceptable, but it DOESNT WORK. Now, you may be like me and figure it’s only about $10, so you’ll try and open up the under diameter with a 1/2” drill bit, and you might think that should work well. Well you would be wrong. The walls are so thin (and they really need to be so that they can dig into the seal), that you just end up losing the first thread. Trust me, you needed that thread. It is now impossible to drive the end into the seal (particularly when it’s under an old corvette) and the tool is slightly more useful than it was when received, but ultimately still useless. Now, let’s talk about the big silver tool that you’re supposed to use to drive the seal back in. It is also at 0.48” inner diameter. Granted, this one can successfully be reamed with a 1/2” drill bit, but what’s the point if you still can’t get the original seal out? Now for the included seal. It’s there, but I don’t think I would trust it. I went and bought one from Oreilly’s for something like $5 (which seems like a lot..) but it actually has smooth walls, unlike the one included with this tool. If you somehow manage to get the original seal out with this tool, do yourself a favor and go buy a better seal. Trust me, don’t waste your time, money, or mental sanity on this junk. ## Frequently Bought Together - Replace for GM Shift Lever Seal Installer Remover Transmission Tool ，Turbo 400 350 300 700-R4 4L60 Includes Seal - PMD Products Shifter Seal fits GM Transmission Turbo 350 400 425 700-R4 TH200 TH325 4L60 4L80E 6L80E AT540 MT640 - ATP Automotive SO-19 Automatic Transmission Selector Shaft Seal --- ## 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.dk/products/421054289-replace-for-gm-shift-lever-seal-installer-remover-transmission-tool](https://www.desertcart.dk/products/421054289-replace-for-gm-shift-lever-seal-installer-remover-transmission-tool) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-13*
