Yes. Use the fluid recommended - Chrysler ATF+4 or approved equivalent.
2000 Chrysler 300M transmission shifting
The 2000 300M with 182,000 miles is shifting a bit funny.
it is shifting a bit odd. 1st to 2nd is sometimes ok and sometimes intermittent with a bit of an extra 'bump" in the shift. not a shudder but a little hickup in the shift. 2nd to 3rd is smooth. 3rd to 4th always is a bit harsh and has a bit of an engine rev before it engages.
Just changed fluid and filter. Nothing unusual in trans, not burnt, but was pretty grey/black and a good bit of fuzz on the magnet.
Put in 1/2 Mopar ATF+4 and 1/2 Amsoil ATF as i've done on all of my Chryslers
for years but it didn't change anything.
No codes show up. Haven't been able to check the CVIs. Can those be checked with a scan tool in the car?
Any thoughts on what might be going on?
Thanks.

Is the Amsoil certified for ATF+4 compatibility?
Did you try retraining it? http://www.allpar.com/fix/trans.html

If the old fluid was deteriorated, the computer will have to learn a bit before shift quality improves.
Of course, you can perform a quick learn with the proper scan tool, which could also check for transmission specific error codes (not just the OBDII Pxxxx codes) and get the CVI values for you. Lots of the shift issues can be related to low fluid pressure.

Doesn't show up on the list. Amsoil claims to exceed some of its parameters, but is apparently not a licensed equivalent.

Both the 41TE and 42LE have solenoid packs, but the 42LE's (LH cars) is internal and generally not audible. The 41TE's was in the front and had a foam pad cover to quieten it.
The 'Zzzztck' was designed out of the sol packs about 2002 and they were silent afterwards.

Bzzzztick is good, Solenoid pack is controlled PWM and under the right conditions you can hear the actuators.
Amsoil ATF claims to be ATF+4 compliant and compatable.
Trans will eventually relearn shift points after a fluid change but you can also manually reset.
Pulling the fuse for the TCM (fuse Q in under hood box) and leaving it out for a few minutes will erase old adaptive memory and accellerate the process.

Resetting is still a good idea. To be sure, I would swap out the transmission fluid and filter anyway, with ATF+4 and dealer filter. The stuff is synthetic regardless - pretty sure ATF+4 has a synthetic base.

If it doesn't meet Chrysler MS-9602, it is not ATF+4. (ms=material standard).
It is considered a 'semi-synthetic' (blended) fluid.

A 'quicklearn' would adjust CVI's for the smoothest shifting. Make note of the CVI values before and after the quicklearn to note the change in clutch volumes from the quicklearn and as a 'baseline' for future service reference if the occasion arises.
A scan tool (DRB III or equivalent) would be needed.

If it is truly non-volatile memory as Mark says, pulling a fuse will do absolutely nothing. That's why it's called non-volatile.
I did do a battery disconnect and it does seem to be shifting smoother but that may unrelated
Will see if i can get a shop to check CVIs and reset (quicklearn) next week.
In the mean time:...For now I need to fiddle with very clunky suspension and partially operating (vent only) ATC. Had the same suspension problem on 02 intrepid. After i had it jacked up to change wheel bearings the suspension got real noisy. Put new struts on Intrepid as the lower rubber mounts were completely gone.
Thanks again.

shifting is kinda back to the way it was. a bit of a hickup (feels like double shift) 1 to 2nd, smooth 2-3 and a hesitation in 3-4
mostly curious if anyone else has had this and how they fixed it.
I hate to not fix things that need to be fixed but Tempted to leave it alone until it gets "bad". I've found 4-5 transmissions around here for $100 to $150 with 76,000 to 120,000 miles (of course some higher). The good (Russ Moore rebuilt) solenoid pack for the 02 intrepid was $140 about 3 years ago. Of course add new fluid filter to any replacement trans.
Plenty of transmisisons around with the bad 2.7s out there.
