89 LX, AOD with 4.10 gears. If i have it floored and basically redlined in 3rd around 100mph is it suppose to shift into overdrive. Its not shifting and i really would like it to or am i being to nervous and letting off the gas to soon. I have tried to do a little speed run a couple times on the highway and i run out of gear so fast in 3rd. Any help please, thx

Beer Rules!

will the aod shift from 3rd to overdrive if its floored?

no it wont. you need your valve body modified so you can run in over drive. i did it and i was only able to max out 3rd at 105 with 410s. problem is od bands arent ment to drive in hard. i did and fried a tranny. youll need a strong tranny to run hard in od with gears. that is why having 410s isnt hte best always.
