Does it blink only in park or while your driving too?You need to get a scan tool on it and check for a code. that should lead you to the problem.unfortunately when this happened to me i had to replace the tranny,mine was blinking in all gears.but definitely check for a code,hopefully it will be something minor. Good Luck

The e-350 is non PSOM.
The sensor you changed is for the ABS.
The speed sensor is on the rear of the trans.
Pull the codes first. From your post i cannot tell if the surge is
motor or a trans issue. Not enough info.

Correct.
On a wag. With the idle/run issue i would take a good look into the TRS system.

in neutral i get no light and idles fine in park the light comes and goes but when its on the engine rpms go up and down, when i put in reverse it takes about 5 seconds and then light comes on always, i pulled the sensor and it looks like its lined up ill have trans shop pull code in morning . i would like to know what scaner tool you guys recomend and are they worth owning , seems the info im getting at local parts store is since its a diesel truck the vtool might not work and is not returnable..

ok i needed my van fixed (no van no work) took it to a shop that i have delt with in the past dropped it off tuesday night ,wednesday morning get a call saying there getting a 705 and 706 code ,range selector sensor 149.00 for the part and 1.5 hours labor saying its a lot of computor related work to set it up. ok 5 0clock wednesday night i call to c if done they inform me that there having a problem with the wirering harness that goes in the sensor . the problem is that 3 off the male pins are loose and corruted they need it another day. on thursday they found anew pig tale harness spliced it in and it can be picked up at 6pm. so when i get there he starts to explain to me that when it shifts or downshifts from overdrive it still might buck and be a little rought on the shifting for the first 50 to 100 miles then he gives me a bill for $603. so on the way home its like the same problem when i tookit there to begin with come on i think i just got screwed. i got a real good drive to do today but have a real strong feeling my van will be heading back to this place on a flatbed!!!!!!!!!!
