Attention: TDR Forum Junkies I'm kinda out of my element here as my auto trans experience has only been a few filter services on my wifes GM (a man'l trans guy). I just did a 30K mi service on my truck which included transmission filter and oil change. Using the fill procedure in the manual, attached below, I add all 4 quarts called for and did not see fluid at the minimum line on the dipstick. Checked for leaks, none... . added another quart 1/2 at a time. Now it is just barely touching the dipstick. This doesn't feel right as the service fill is listed as 4 quarts and I'm at 5 quarts and still doesn't seem like enough --- any advice?
From the factory service manual:
AUTOMATIC TRANSMISSION
Service Fill - 48RE 3. 8 L (4. 0 qts. )
Overhaul - 48RE 14-16L (29-33 pts. ) L
TRANSMISSION FILL
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 MoparT ATF +4 to transmission:
a. If only fluid and filter were changed, add 3 pints (1-1/2 quarts) of ATF +4 to transmission.
b. If transmission was completely overhauled, torque converter was replaced or drained, and cooler was
flushed, add 12 pints (6 quarts) of ATF +4 to 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 noticably 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 and 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.
