The wire has most likely broke in the column. This is why it may not light. If it does not light. How can to tell if its flashing? You cannot! Check the wires from the od cancel switch down into the column. My bet is your trans is in limp and you cannot see the lamp flash. Then you need to scan for the codes. So you can repair.

I had a similar issue when I put my edge tuner in my truck, going uphill or hard of a light it would damn near break my neck from second to third. I kept thinking I'd look back and see the tranny on the ground behind me. Pulled the chip and no problem. No power either

That seems to be a common thing, I mean edge tuners are good, my dad has one on his chevy duramax and it works fine. So I guess it means 7.3s and edges dont work well.

that was the sense that I got. I'm a rookie at this whole thing. CH Joe turned me away from the edge pretty quickly. I'm gonna ebay the thing and go with dp or wildman. Mostly I want the extra mileage, ooohhh and yes I like to smoke the occasional teenager in a chevy at the lights when the opp. arises.

Its probably rear clutches! Im guessing you have whip lash neck braking shifts in 1st and 2nd. If this is the case its time to pull it and have the internals rebuilt! The cost to me on my bitchin rebuild including, 2 six pinion steel planetaries, metal lathed 4 clutch drum to 5 clutch drum and had the complete internals rebuilt, shift kitted and what not was truly about a 2200 job but i got it for 1600 so thats what i would suggest you do ne way. If you go with just a small fix here and there like replacing the clutches and what not your still gonna have the same problems you have now just time bomb ticking. So i would recomend you get it done right the first time! I would suggest going to a manual tranny shop and asking about who is good for auto tranny shops because i know before i was workin for the shop i am working for now i went to aamco and they were gonna charge me 3000! So I would suggest you go with a shift kit-150 new torque converter /300-1000 depending on billet or not, clutches and all internals-? 5-600 in parts dunno depends on whats tore up or not! NOTE TO SELF YOU COULD POSSIBLY ALREADY HAVE A SHIFT KIT IN THERE BUT THE SYMPTOMS YOUR DESCRIBING COULDNT POSSIBLY BE NORMAL!!! I DONT THINK! But the guy who rebuilt my tranny has been workin on trannys for 27 years, thus he is damn good and i would recomend getting the Pressurizer box from Superior to raise the line pressure in the transmission pump to give you even better shift. But im steppin off my soap box now so let me knw if you have any questions.
After reading your post I will now say that I could tell your a rookie tranny guy with minimal shop time under your belt and for that reason alone I will take it easy on you. Your wrong about any 97 having a 4r100 from the factory. There might be a few boys runnin around with the 4r100's in their OBs trucks but rest assured it did not come that way from the factory. Second, raising the line pressure electronically will put major stress on the already weak pump in the transmission. Every tranny guy who has had their hands in a fair share of e40D tranny knows that much. Thats why performance valave bodies or a shift kit of some kind is installed into a rebuild tranny that may be seeing more power then stock at any level. Rasing the line pressure manually dosn't put added stress on the pump therefore helping prolong life of the rebuild. I dont mean to be a d1ck but im sure thats how it is coming across. Best of luck in the tranny world

Thanks!

Ok well yes i am new to the tranny world but i understand that 4r100 did not come from the factory in 97's but it did in 99 and thats the only reason i said 97 no worries. Not tryin to fire back, just clarifying i am rookie though thanks for the correction.

umm last time i checked anytime you raise line pressure, electronicly or mechanicly you are forcing the pump to work harder and are putting more stress on the seals

Right from ford they raise the line pressure under some conditions.

I raised my pump pressure for a few reasons. A major one is wanted more volume in areas. I cannot open up the circuits, so the only way is to increase the pressure to get more volume. I have at least 1/2 dozen induced leaks in my trans for full time lube reasons.

Way it was explained to me was that VB re-route fluid to increase line pressure with little to no added stress on the pump. Electronics just jack up the pressure to increase shift firmness which intern adds alot of stress on the pump. I believe you might at one point in time have even backed that info up prior to this "''love/hate" deal between us
