Was out wheelin last night, one of the atf lines to the radiator came off so it went pretty low on fluid. Truck would run but when you put it into drive it would only rev up and would not catch and start moving. Put 3 quarts of atf fluid in will now catch but when starting from a stop takes a second to catch. Wondering if there is anything I can about it besides having to replace the tranny. The truck is a 99 ext cab 4x4 trd with the 3.4 liter engine in an automatic. Any help would be greatly appreciated.
