Transmission fluid guidance needed

[tbenner]

Hello folks,

I have had the 95 E320 wagon for 5 weeks now and have not yet changed the trans fluid and filter. Part of the reason is that I have searched here a number of times and gotten spooked by some postings where the trans was working fine before the fluid change but not after. Right now the fluid is red and OK looking but I have no idea when it was last changed. Same with the diff.

I was thinking of changing to Mobil 1 ATF. Some posts say it cured their leaks and some say they saw more fluid after. Would you advise to use Mobil 1 or stick with normal Dexron/Mercon III? The trans is working just fine now. SHould I anticipate problems?

For the diff, should I stick with dino or can I refill with Redline MT90? The MT90 worked great in the Triumph trans and diff but this is a whole 'nother kind of car. Any suggestions?

Thanks!
