1997 Thunderbird 4.6, 1998 Mark VIII LSC
This is on the Cougar. I just changed the tranny fluid a couple days ago, but the issue was persistent before and after the change. First off, the 1-2 shift is just as quick and snappy as my J-modded 97 and this is an untouched valve body, so would I be correct in assuming this would most likely be a broken 1-2 accumulator spring? The main issue for my post however is that occasionally the car seems to slip out of 1st gear when I come to a stop then start moving again. I'll open the throttle a bit after a stop and the engine will just rev, then a second or so later the transmission will engage again and I'll procede on my way. This has happened maybe half a dozen times in the 300ish miles of city driving I've done on the car thus far. Other than this, the transmission seems to shift as it should (although a bit slowly, especially when you're used to the J-modded shifts ). Any ideas?
