Thread: starting off in 2nd gear..90 AOD

  1. #1

    Default starting off in 2nd gear..90 AOD

    So it seems like the car is starting off in second gear from a stop. What could be the cause? If I pull the gear lever all the way down (2) I have 1st gear and if I floor it in second with the lever in (D) it down shifts into 1st. Any ideas?
    Thank you

    I had that problem with a totally different trans and it was garbage in the governor. With your other low rpm shifting thing, I wonder if thats not the problem.

    Thank you Brown Muscle and Gadget. I'm going to have a look into it this weekend.
    Might be time for a set of wide ratio gears and a little higher stall converter along with a rebuild.

    Definitely some junk in there somewhere.

    I lost first in my 88 for about a week. It was cold AF and I guess condensation froze it up. I did not have any access to first, manual, downshift, nada. First came back after a long highway run (two hours) and lived happily ever after for the next 12 years (until 1-2 started to slip).

    Do not do a trans flush.

    easy enough to remove and inspect the governor. Just pull the tailshaft and its under there. If I remember right the actual working part just unscrews from the part that mounts it to the tailshaft. Not much in there, spring and a piston basically. Make sure its not packed up with trash.

    Thank you David.
    Today I put some Seafoam for transmissions in, hoping to free up any sticky valves. I drove it around for 33 miles in neighborhood conditions. I manually shifted from 1-2 many times during this outing. I found an open stretch of road and laid it into it a couple of times. Once manually shifting from 1st to 2nd and also in D and letting it shift by itself. Each time in 1st gear it laid 2 patches of rubber down about 3 feet long and chirped second. I'm just going to drive it like it is and prepare for a rainy day and get a performance transmission or parts when time calls.
    On a side note, on the back road I got to watch a 70's Challenger get it on thru the gears, It was a built beast and defitinely a big block. The tires got skinny when he took off and he wound it up in each gear. Sad though, I think it was an automatic.
