thanks for the response. I saw your response and immediately had to go back to my posting to re-read it.
I described my problem incorrectly from a technical standpoint. What I meant to say was that the vehicle will operate just fine in either 1st gear or reverse. No problem at all, but when you accelerate and expect a shift change, it doesn't take place and the engine reaches as high as 3000rpm before I slow it back down. It simply won't make the change any longer.
This happened instantly after a small radiator hose attached to a cannister on the right side of the radiator suddenly popped off and spewed anti-freeze all under the hood. Once I replaced the hose and clamp and left the parking lot, the transmission began shifting erratically but I made it home. Now when I try it, it won't shift out of 1st gear. Or at least not up to 3000 rpm anyway.
I was almost certain that the anti-freeze had shorted something out or blew a fuse to the transmission ECU if such a fuse exists.
my number is 850 284-2300 if you still wish to contact me. I tried reading up on the ecu and if I had a way to test it, I'd almost bet something happened to it as a result of the radiator incident.
