My '93 FZJ80 needs a transmission fluid change. However, I'm not doing a complete system flush just draining the pan. I see the system capacity is 12.6 qt but I know I cannot add that much since I never drained the system. So, how much do I add to start ?

I should have measured what I took out:doh: but It's a little late for that now...

Thanx as always...

Have you done a complete flush? If not, here is your chance to do it! Of course, you will have to guesstimate how much you took out before taking her to the service station, as you have to her filled up! You may be out a couple of bucks, but don't drive it with that much fluid gone. Good luck!:cheers:

PS. Have you changed/flushed your power steering fluid?

The accurate way to do it (if not doing a "full" flush) is to drain from pan, and then dump that into one of the 4quart oil jugs that has a level window on it. This way you know exactly how much came out and how much needs to go back in. Assuming of course the level was correct when you started.

When I drained mine last weekend, it measured out to 3.6 quarts. I plan on doing the drain/fill 2 or three times with some driving inbetween, and then every oil change.

That's assuming that the person before you put the correct amount in it!

Get a case of transmission fluid. Especially if doing a flush. You should have enough left over to flush and fill the power steering too.

I used Napa fluid as it was way cheaper than the synthetic MObil 1

Check the dipstick before you begin while it is cold, score it and then fill it back to below that level if you are unsure if you currently have the correct amount or to that level if you are sure that you do. Then drive it around after replacing fluid, get it up to hot operating temperature. Then add as necessary to get the fluid level to the HOT line.
