Spring has arrived here in the Flathead (Whitefish) so I got my 98' 4Runner out for a spin. Other than a couple short drives she has been parked in the shop all winter on a trickle charger. I drove from Whitefish to Kalispell and noticed that once in overdrive the transmission is jerky if I try to speed up a bit. I am not talking kicking into passing gear speed up I just mean if I have slowed a bit and apply light pressure to speed up. I cannot recreate this issue if I turn OD off. Furthermore, all shift points are smooth otherwise. I have also checked if there is a possible misfire, etc, but it appears the problem is the transmission or possibly the torque converter. All this said, back in the day I would just tear into her find and fix the problem. That said, I haven't the time am I am looking for a creditable 4Runner transmission mechanic near me. Please let me know your mechanic recommendations or if you feel my problem is a simple fix please let me know. Shift point solenoid? Plugged Valve body/filter? Who knows...
