    The Allison MH3000 in 2003 American Tradition Cummins ISC 350 was inadvertantly left in drive with the parking brake set at 1K rpm for about 15 minutes ...when noticed trans was returned to drive...the Silverleaf Analyzer indicated a trans temp of 245 degrees and within 5 minutes temp returned to below 200 degrees....have driven approx 1,000 miles since with no problems noted...Trand oil changed about 4K miles ago Dextron lll...should I change it again or is it not necessary....Thanks

    Probably didn't hurt it if it never got above 245. What color is the oil on the dipstick? Any burnt smell?

    More than likely it was'nt hurt. For piece of mind, I'd start fresh.
