When am driving my ford transit connect 2012 especially when am on low speed or am climbing hill the suddenly my speed reduces and a code is thrown. Sometimes my dashboard odometer display will go blank for awhile and come back on. On pressing the gas paddle I feel the engine run more fast but no output in wheels. When I used OBD2 reader it tells me output speed sensor and low temperature.
Would I need to just change my output speed sensor on my gearbox only or what can I do to solve the problem.
Also when am climbing small hills to sometime my engine overheats even thou my fans are working.
