Honda B Series Shift Rod Oil Seal - 91215-689-013

If you're seeing transmission fluid dripping from your shift rod area, or you keep topping off your trans fluid and can't figure out where it's going, this is the seal you need. The Honda B series shift rod oil seal (part number 91215-689-013) sits right where the shift rod enters your transmission case. It's a rubber seal, and like all rubber, it gets hard and brittle from years of heat cycles and oil exposure. Once it hardens, it can't conform to the shift rod anymore, and fluid works its way past it. The fix is a new seal - it's a three-dollar part that takes a few minutes to press in.

Why Your Shift Rod Seal Leaks

The shift rod moves every time you grab a gear, and that seal takes the full brunt of constant motion, heat, and fluid contact for years on end. The rubber eventually loses its elasticity, compresses permanently, and stops making a proper seal against the rod. You'll usually notice fluid weeping from the shift rod area at the transmission case - sometimes just a damp spot, sometimes a steady drip depending on how far gone the seal is. You might also catch it by checking your fluid level and finding it lower than it should be without any obvious reason. Either way, this seal is the culprit.

Replace It Every Time You Pull the Transmission

Seriously - any time your transmission is out, this seal gets replaced. No exceptions. It's around three dollars and takes two minutes to install. If you skip it and the old seal leaks after you button everything back up, you're pulling the entire transmission again to fix a three-dollar part. That's a full Saturday wasted to save a few bucks. If you're doing a clutch job, transmission rebuild, or a B series transmission swap, just add this to your parts order now so it's ready when you get there.

When you're installing the new seal, clean out the seal bore in the transmission case first. If there's any old seal material stuck in the bore, scrape it out completely before you press the new seal in. Press it in straight - if it goes in crooked, it'll leak. Lube the seal lip with a little fresh transmission fluid before you slide the shift rod through it.
