Transmission and Vdrive Service

[DOCDRS]

Performed my 15 hour service on these 2 components. Took about an hour. Interval changes on these fluids are yearly, the screens on the tranny and vdrive I'd say every 300 hours ,but jmo.
Tools - 1/2", or (13mm on newer years) wrench, fluid extractor, sae 30 oil 1 litre, atf dexronIII . transmission fluid 2 litres, paper towels

remove tranny fluid , and vdrive fluid with extractor

[DOCDRS]

then using 1/2 in or 13mm inch wrench remove tranny screen coverplate bolts located on bottom of tranny in a near impossible place to access. As i didn't extract as much fluid as i thought i should have i prepared with papertowels underneath



alot of fluid came out when the coverplate was removed and there was some dbris on the screen...small white in colour partcles, but not too bad overall.
screen was reinstalled with coverplate bolts torqued and fluids replaced to top fill lines using sized funnels. tranny hole is bigger and fills quick, vdrive is smaller and slower to fill. Vdrive took about .95 litres, tranny about 2 litres but didn't keep track and over filled and had to remove some.

I prob should have bumped motor over after tranny fluid extracted maybe to remove fluid in tranny cooler, i did have the boat tipped bow down on the trailer , maybe its just the nature of the beast but seemed to be about 6-8 oz of fluid that came out the bottom.

I will have to run engine and recheck levels , i assume i will have to add tranny fluid as it should be checked after it has been run so fluid is in the cooler. I will update how much later.

All in all not a difficult procedure just hard to get to the 1/2 screen coverplate bolts.

Very nice. Thanks for the documentation and good photos.

After extracting as much fluid as you can out the dipstick hole, slide a pan underneath the vdrive and remove the square head bolt on the back side, center, very bottom. You'll get quite a bit more fluid.

Once you've done that you can remove the 15mm square head bolt on the front left side. This is the magnet and should be wiped clean.

... just hard to get to the 1/2 screen coverplate bolts.

I'll second this... huge PITA on my boat.

Was there much on the vdrive magnet?

Was there much on the vdrive magnet?

Yes. Not sure how to quantify how much, but enough that I was glad I did it. The trans screen on the other hand... not sure I'll mess with that again for quite awhile.
