Transmission slippage following fluid change

[BearHug]

Hello everyone,

Long time reader, first time poster here. Trying to figure out a small issue. Having some transmission slippage following a fluid change.

Just changed my car's transmission fluid and filter for the first time since buying it about six months ago -- currently, has about 118k on the clock. Had no issues before change just thought it a good idea to swap in some fresh fluid.

After dropping the pan, replacing filter, and re-screwing everything on with a clean gasket I added about two quarts of Mecron V. I ran the car through all the gears without issue, but now I'm starting to notice some slippage. A check of transmission fluid shows it's in the normal range.

I'd say it's worst when putting the car in reverse. Instead of instantly going into reverse it takes 3-4 seconds of lag time before engaging. This has also happened in OD and drive but not as bad. After driving the car for a while it seems to clear up. Just wondering if anyone has any ideas on the issue?

Thanks and Happy 4th of July.

Its possible the torque converter is not fully filled yet. Might need to add a little more oil

Definitely sounds like it needs more fluid. 2 quarts isn't enough when dropping the pan. When the fluid warms up, it expands and you end up with 'enough' in the system to get it to work. Add 1/2 to 1 quart and start it up, drive it around and once it's warm, check the dipstick and add as necessary.

Thanks, followed your tips and topped it off with half a quart. The little delay is virtually gone. Will give it another gander and top up as necessary.
