TH350 27 Spline Driveshaft Slip Yoke - 3R/1344 Series For GM 200-R4, TH350, 700R4, 4L60E Transmissions

GM transmission owners, this 27-spline slip yoke is exactly what you need for your driveline repairs or upgrades! Specifically designed for GM transmissions with 27-spline output shafts, including the popular 200-R4, TH350, 700R4, 4L60E, Powerglide, T-5, T-6, and M21 units.

The 3R/1344 series designation means it uses standard U-joints like the 5-3147X, 5-795X, 2-3011, or 3R51-20, which are widely available at any auto parts store. The hub diameter is 1.502 inches with a 1.172 inch spline major diameter, and it's 6.750 inches long - all standard dimensions for these applications.

What's nice about this yoke is that it's fully splined with no vent hole, which is what you want for smooth operation and proper lubrication. The quality is brand new, not some questionable rebuilt part that might have hidden wear or damage.

Installation is straightforward if you're familiar with driveline work. You'll need to transfer your U-joint from the old yoke (if it's still good) or install a new one. The splines should slide smoothly onto your transmission output shaft without forcing anything.

Before ordering, definitely confirm your transmission's spline count and series. This is specifically for 27-spline applications - if you have a different spline count, this won't work. The 1-year unlimited mileage warranty gives you confidence in the product quality.

Whether you're rebuilding a transmission, replacing a worn yoke, or building a custom driveline, having the correct slip yoke is crucial for proper operation and safety. This one delivers OEM-quality fit and function at a much more reasonable price than buying from the dealership.

For the price with the warranty coverage, it's solid value for anyone working on GM transmissions. Just make sure to double-check your application before ordering to avoid compatibility issues.
