'92 Automatic Tranny Fluid Question
You'll need about 18 quarts of ATF if you're going to drain the converter. Mine used Mercon (not Mercon V).
I pulled the pan (Metric bolts, 10mm, I think).
Clean around the pan edges. Pull the bolts on the sides first, then loosen the fronts, then remove the rears. Oil will mostly run out the rear. Pull the pan the rest of the way off and clean it surgically clean, especially on the inside. Pull the doughnut shaped magnet out and clean it really well. I've found air gets whatever shavings off of it fairly easily. Pull the filter out and slip the new one in. Put the pan back on with the new gasket and torque the nuts evenly and diagonally. I think it's 14 ft/lbs, but I'm not 100% sure.
Then I drained the torque converter. I think the rubber plug you're referrring to is at the bottom of the bellhousing. Pull it and rotate the crank by turning the vibration damper bolt at the front of the engine (I think it's a 1" socket) until a small bolt comes into view. Unscrew the bolt and the converter will drain. It will take a while; there's a lot of fluid in there and the hole is small. Replace the bolt and the plug.
Put a few quarts of fluid in then start the truck for about 15 seconds. Put a few more in and start it again. After about 12 or so, I would say start checking the level carefully and don't overfill. I overfilled and had to pull the rubber plug and bolt from the bottom of the TC to drain a little.
This made a huge difference in my transmission shifting properly (not sluggish).
I wouldn't start the engine with the TC partially-filled. The vanes slapping the fluid could bend or break them. Fill slowly until it starts to back up the dipstick tube before cranking. If you have too much, drain or siphon some then.
Your shifting performance really increased?
Hmm... Maybe I'll have to try that, mine shifts kind of sluggish..
How much did all that fluid cost?
Anyone have an idea?
Would I notice anything performance wise if I changed the fluid?
