Jerking under load
I know there are quite a few threads on this but I still haven't found an answer that worked.
Ive had this problem for a while now. I notice it is common on the SOHC rangers and saw the TSB but mine is a 98 with the 4.0 OHV and auto transmission. Unlike the threads with the newer rangers, mine doesn't jerk while just crusing, I have to put the engine under load at low RPMs do it only really happens going up hills at 45mph@1500rpm. What actually causes the jerking, is it a trans or engine problem? It feels like the TC keeps unlocking/locking but it will jerk 12 times going up a hill.
I would like to solve this problem mechanically but if not, can a tuner with the programming software fix this? I would like to get a tuner to lower the shift points and increase the load but not if tthis problem persists.
Im running a paper filter and cleaned my MAF sensor not too long ago.
