My car shifts well, but after reading the rave reviews about AMSOIL Synthetic Manual Synchromesh Transmission Fluid posted by AMIRZA786 in his excellent thread Changed MTF to Amsoil Synchromesh, I am Happy! I thought I would give it a try. While this isn't a difficult DIY job, I'm posting the instructions for two reasons: 1. Help others learn their way around under the hood. 2. Are these MT's different? In AMIRZA786's post, he mentions needing two sizes of crush washer. A 20mm Washer, Drain Plug and a 6mm Washer, Sealing.
When I changed my MTF, I didn't find a need for the 6mm washer. The fill cap on the top of the transmission and the drain plug on the bottom are identical in size and the drain plug on the bottom uses the 20mm washer.
Did anyone that did this themselves need the 6mm washer? I'm just curious if there are variations in the 10th Gen MTs.
Tools used: (Not shown in this picture are the oil drip pan and long neck funnel)
Instructions:
1. Loosen the fill plug in the top of the transmission (its to the left of the airbox) using a 3/8" square drive. I used 15" of extensions and a breaker bar.
2. Say hello to your gears! (The MT is not full of oil, 2 quarts is all that's required. I drained exactly 2 quarts from mine).
3. Put the car on ramps/lift/jack it up to get underneath.
4. Remove belly pan. There are 10 fasteners.
5. Position drip pan. I put some boards under mine to raise it up so there would be less of a mess from splashing.
6. Remove the drain plug. Located just to the right of the rear motor mount. Used breaker bar with 3 inch 3/8" square drive. Its identical to the fill plug removed from the top.
7. Let the MTF drain fully.
8. Put a new 20mm washer on the drain plug. In the picture below, the top plug is the fill plug (no washer) and the bottom one is the drain plug with washer.
9. Replace the drain plug with washer and tighten. If anyone has the spec torque value, please post.
10. Fill the MT with 2 quarts of MTF.
11. Replace the fill plug and tighten. If anyone has the spec torque value please post.
12. Done! Clean up and enjoy the smooth shifting!
