The next problem I would like help with is the transmission;
1994 Super Coupe 4R70W automatic
What it is doing in a nut shell is: Car warmed up to operating temp, cruising down the highway at 70 + mph and it will down shift out of O/D into 3rd gear. The RPM will jump up to about 3.2K then it will then shift back up to O/D. I am also under the opinion that this co-insides with hitting a hard bump in the road.
Is it likely that there is a loose connection? Would it be internal or external to the tranmission? It does not appear to be an issue with the switch on the gear selector on the consloe.
SC has 116,030 mile on it and had the tranny rebuilt at 90,000 by a man that can do a good job if he is in the mood.
Through me some thoughts gang..............
