Hi, I've recently had the th350c in my elky rebuilt and everything has been fantastic with it until the rooster comb providing the detents for the gears came loose. It would cause the roller to contact it at a weird angle and woudl throw off the detents so that the shifter would always detent between gears and not actually engage. I ended up taking the pan off, finding the issue and removed the rooster comb and reinstalled it to get it properly seated again. Removing it cause some fluid to come out wich I thought nothing of. I torqued the rooster comb back down properly and then I ran the car and let it idle in each gear for about a minute each. The very next morning after doing this I've been having an issue where when the car is started cold and driven when the thermostat hasn't opened yet (unrelated but gives a frame of time of how long the car has to run before this issue doesn't pop up) I would drive about a quarter mile to half a mile or so and when I get to my first stop, the transmission would lurch forward like it does when I first put it into drive. I've had issues where I would come to a start to make a right hand turn and when I go to take off, the engine would rev up and then the gear would engage and do so pretty hard since obviously the engine speed is up. If I drive for about 10 minutes and everyhthing is up to temperature It won't do this again until the transmission is completely cooled down to ambient temperature. I can't figure out what the hell is going on and what to do about it. Before the transmission was rebuilt I drove it for about 3 years and have never once had this issue. I've tried searching on this forum and have so far come up with nothing. I've tried googling and have also come up with absolutely nothing. Anyone here ever come across this problem before? Thanks for any input anyone can provide. For now I've been allowing adequate time for everything to get up to temperature before taking off down the road to avoid the transmission slamming itself into gear if I try to stop and go quickly. P.S. it doesn't seem to matter if I stay in 1st, get up to second or even 3rd. It always happens when I approach and/or come to a stop and everything isn't up to temperature.
