First time it happened both "sport" & "manual" lights on the dash started flashing and when I applied the gas, it seemed that the transmission was in low gear. Second time, both lights appeared and I immeadiately turned engine off (without trying to move forward)and removed the key. Both times after I shut the engine off and re-started all was normal. Happened twice this week. Anyone experienced this before? Was I shifting through the gears too fast and confusing the transmission or should I be more concerned? I have 49,100 miles and would like to get it to the dealer ASAP before the 50,000 mile mark. Thanks in advance for any feedback.   Dean Brown (Deanbrown3d) Senior Member Username: Deanbrown3d Post Number: 709 Registered: 02-2002 Posted on Thursday, August 07, 2003 - 08:56 am:    Steve Call the dealership asap and ask them if you can drive to them or if they should come trailer you back. I don't have my shop manual right here (its in the car if you desperately want) but I remember its the most serious signal from the transmission ecu.   bluesman (Hywy61) Member Username: Hywy61 Post Number: 55 Registered: 02-2003 Posted on Thursday, August 07, 2003 - 09:11 am:    It has done it to me twice - check your manual. I took mine in and they said it was nothing - translation - "we have no idea". It seems to do it when I am parked on a steep hill and then place the truck in drive. It feels like the transmission is out of line (for a lack of a more techincal term ). Bottom line i would take it in since you are still under warranty. When I took mine in last time it did it I ended up with a totally unrelated valve job - $2600 covered on their dime. If i find the codes in my workshop manual i will repost.   bluesman (Hywy61) Member Username: Hywy61 Post Number: 56 Registered: 02-2003 Posted on Thursday, August 07, 2003 - 09:14 am:    oh yea - mine is a DII 2000 - 46K   OLIVER CLOTHSOFF (Everythingleaks) Senior Member Username: Everythingleaks Post Number: 293 Registered: 10-2002 Posted on Sunday, August 10, 2003 - 02:05 am:    It should store faults in the EAT (Electronic Automatic Transmission) ECU. I would at least get it documented that you have a problem before the magic 50k mark.   Phillip Perkinson (Rover4x4) Senior Member Username: Rover4x4 Post Number: 378 Registered: 02-2003 Posted on Sunday, August 10, 2003 - 08:34 pm:    m = mud s = soon   Mud Man (Clarance) Member Username: Clarance Post Number: 67 Registered: 02-2002 Posted on Monday, August 11, 2003 - 09:21 pm:    Mine did at 74k and i needed a new transmission. If you call them, they'll tell you trailer it in. I would and at least get it on file that you had issue with it.   Steve Fesperman (Fespy00) New Member Username: Fespy00 Post Number: 4 Registered: 02-2003 Posted on Tuesday, August 12, 2003 - 09:33 am:    Thanks for the feedback. The dealer will have it on Wednesday morning. According to the manual, if the situation I describe happens, shut-off and re-start is recommended. I have driven it without incident for several days. Dealer did not have recommendations about not driving. Anyway, it will be in the shop and have the problem recorded at about 49,500 miles. Hopefully not a big deal, but we will see.
