ford AX4S tranny problems

[rpbenisek]

Have only 78K miles on rebuilt and now i am experiencing a jerking -missing
issue especially when accelerating or uphill driving, I have no codes that are set and no O/D blinking. It sure acts like a motor miss (electrical) and or fuel problem, just driving a constant speed it drives ok it seems to possibly occur at the 40-50 rpm. no i have not yet taken it to a tranny station to have it scanned
I just want some foresight on the issue from you tech guys as i repaired and fixed many problems with this Auto Forums web site.(po171-po174 as an example) i'm wondering if any other sensor could be the problem. I think I know the obvious but still have wishful thinking.

what year van? 78k (as in 78,000 miles) since rebuild? That's a fair number of miles - sad to say I know. Have you confirmed that the fluid is completely full? The dipstick is a bit misleading and if you're driving uphill with a miss you may just be faced with a low fluid level condition. When was the last trans service done? What sort of warranty was with the rebuild?

Try reading the OBDII codes.....MANY transmission faults can show up in the OBDII code set that you can read same as you do the P0171 / P0174 type codes.
If you have them read for you....make SURE to ask for the actual numeric codes.
I ran into strange transmission issues while on a trip......code reader brought up the Vehicle Speed Sensor (VSS) as the cause of my problem.
In short....a quick code read might speed you to a diagnosis.......no guarantee that you will like it, but at least you will know.
