GOT TO HAVE ALL THE SAME SIZE TIRES ALL THE WAY AROUND, ALL WOREN EVENLY ,,NO NEW TIRES UNLESS ALL ARE NEW THE HEIGHT HAS TO BE ALL THE SAME ON ALL TIRES. EXPECIALY WITH EXPECIALY WITH ABS BREAKS,,YOU CAN REMOVE FRONT DRIVESHAFT IF THE TIRES ARE NOT ALL THE SAME SIZE FM LANCASTER,OHIO

change the fuel filter first

Check the linkage under the vehicle from floor shfter arm to PTO arm. ( a rod between the two) There should be a coupler on the rod that has probably come loose and moved. Adjust back to proper position and secure. You will probably be able to see the original position of the coupler where it was originally if it did slip. Let me know how it works out.

see transmission shop

check fuse if good need to check power at switch's possible loose wire behind dash or short

why is it I can post an answer but can't get an answer for free

ABS LIGHT ON AS WELL?IF SO..I WOULD LOOK AT ABS SENSOR IN REAR DIFFERENTIAL..GETS SPEED SIGNAL FROM THIS SENSOR AS WELL..USES ONE IN TRANS FOR TRANS SHIFTING

The best way to do that is to start the engine put the transmittion in neutral with your foot on the brake and pull it out of 2hi,,,put the trans in park then move shifter to 4 hi or lo.

I have the same problem with my 98 mpv when I flip the switch the light just flash's
