Since 187k when I acquired my 41TE equipped van, my dad said it's a bad idea to change trans fluid on a trans without knowing the service history. Fast forward to now, it has 238k and I've revived the idea of a pan drop & filter change. Only issue i've had with the trans in my 50k mile ownership is 3rd gear (TC Lockup) has a noticeable slam when going in and out. Fluid colour isn't burnt but it looks worn out, level is OK
ATF+4 Change on unknown service history?

If the transmission doesn't have a drain plug, get an aftermarket pan that has one. Refill with Redline C+ which is the best thing to use where ATF+4 is required.

A few drain and refills may help the situation.
Fluid color is never a sufficient indicator of fluid condition.

I would surely do a pan drop and filter change on your 41TE. That transmission can be troublesome and affected negatively by worn out fluid.. I would stick strictly to an approved ATF+4 fluid and wouldn't use anything else.
^^^what they said^^^
Change it. Change it now. At 238k the additive pack is likely depleted.

If it was my vehicle, I'd do a pan drop without hesitation.
Be happy it's not burnt.
238k in Indiana! How's the rest of the van?

Only deep rust is on the jacking points, surface rust everywhere else
Especially with some of the beating I've subjected it to, but I guess a transmission cooler on a Chrysler pays off big time
