I recently replaced the transmission in my 98 TJ. About 8 months before was the engine. Both are remanufactured and not junkyard specials or rebuilds. When I had the engine replaced I get the tech a distributor I bought from Rock Auto, the OEM was starting to squeal so I thought the bearings were going bad.
Now when I am driving and I give it gas it wants to back fire, bog down, surge then go. I am wondering if flashing the ECM will set it back into Adaptive Mode and relearn. I have been looking at these threads:
but they all seem to be XJ related. I am not sure if this will work on my TJ. I don't want to fry the ECM and be totally screwed so I figured I better ask here. I have already replaced the plugs, wires, cap/rotor, MAP, TPS, and both O2 sensors.
Another thing I am wondering is if this reset does work while it is in adaptive mode will it relearn the manual shift points too? I have 4.56 gears, Truetrac f/r, 5spd, and 35" tires. Seems when I drive and hit 5th the shift light will stay on until I get to about 65/70 mph. All the shift points seem to be sooner now that I have the larger tires on it.
