What about torque converter... After removing all the transmission, do we need to add oil to the torque converter before re-installing transmission?

I've never owned a 32RH personally, so I'm reluctant to answer. @Jerry Bransford, do you know?

No, it will fill up on its own when the engine is running and the transmission is in Neutral. Nope it won't refill if the transmission is in Park so do shift to Neutral to get the ATF pump to run. That's also how you have to check the ATF level, with the engine running and transmission in Neutral. When the transmission cooler, torque converter, and 32RH are empty it'll take nearly 9 quarts of ATF+4 to refill everything.

You can partially fill the torque converter before reinstalling it to help it 'hook up' more easily in the beginning.

Drive and check the fluid several times, the ATF level will usually drop as it circulates so while it may be full in the garage, odds are it won't still be full after driving it.

Automatic Transmission Fill Procedure per the FSM

32RH and 30RH (97-02 3 spd auto)

To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
  1. Remove dipstick and insert clean funnel in transmission fill tube.
  2. Add following initial quantity of Mozart ATF Plus 3 to transmission:
    1. If only fluid and filter were changed, add 3 pints (1-1/2 quarts) of ATF+4to transmission.
    2. If transmission was completely overhauled, torque converter was replaced or drained, and cooler was flushed, add 12 pints (6 quarts) of ATF+4to transmission.
  3. Apply parking brakes.
  4. Start and run engine at normal curb idle speed.
  5. Apply service brakes, shift transmission through all gear ranges then back to NEUTRAL, set parking brake, and leave engine running at curb idle speed.
  6. Remove funnel, insert dipstick and check fluid level. If level is low, add fluid to bring level to MIN mark on dipstick. Check to see if the oil level is equal on both sides of the dipstick. If one side is noticeably higher than the other, the dipstick has picked up some oil from the dipstick tube. Allow the oil to drain down the dipstick tube and re-check.
  7. Drive vehicle until transmission fluid is at normal operating temperature.
  8. With the engine running at curb idle speed, the gear selector in NEUTRAL, and the parking brake applied, check the transmission fluid level. CAUTION: Do not overfill transmission, fluid foaming snd shifting problems can result.
  9. Add fluid to bring level up to MAX arrow mark. When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.
First it says to "Add following initial quantity of Mozart ATF Plus 3 to transmission:" And then below it lists the correct "ATF+4". I assume the first is a misprint in the FSM? Might want to change that if I'm correct. Maybe I'm reading this wrong?

I'll keep looking but is there an instruction posted for removing AT trans fluid, filter and gasket/pan someplace?

Should be ATF+4. Looks like a misprint to me.

Great info in this thread.

I'll be installing a new gasket/filter and trans fluid this weekend, on my 1998 TJ 4.0 32RH auto trans. The new gasket is supposedly rubber.

Should I use some gasket sealant/dressing? If yes, is there a recommended sealant, and should it be on both sides of the gasket?

Maybe dumb question. Going to be changing coolant for first time. Is the 10.5 quarts the amount of non-premix coolant I need to get or do I only need to get half that cuz the rest is the water I will add?

I was told steering fluid needs to be changed at 100k miles. Is that correct? Any recommended brand and type?
Thank you

Hey Guys!

How often the manual transmission fluid should be changed? (I have the Nv1500 transmission)
