Down shift at 70 MPH ??

Has any one, while travling at 70 mph or faster, in OD, had a auto tranny, for some unknown reason down shift into 3 ? ???
I expearenced this the other day, didn't know what was going on at first till I saw the light on, on the OD button.

So! does anyone know just what is going on when this happens?

OH Sick.

 

I've left mine in 3rd at 80 mph before for a couple of miles. Haven't seen any long term effects. Sat right at 3200 rpm.

 

Blue: Did you purposely do that or did the tranny mysteriously down shift because of a malfunction ?<br><br>Oh Sick

 

Were you in cruise ?

 

YEA.................I think thats what OD is!

Sorry about that. NO I was not.

 

Just got up........getting all mixed up here. ???

 

Hey not a problem, reason I asked is cause I was in cruise at 75 and not thinking hit the button to down shift, I thought I lost an engine. Noise was unreal. Tach went to 3300 but no problem. I guess we all do some dumb things sometimes.

 

To bad about that SideKick. Mine did it by its self, I had nothing to do with it. Im still trying to find out what could make it do that.
