Brand new (about 150 miles) Darrin built trans. Shifted fine prior to getting dyno tuned last week. And was fine for about another twenty miles after tune. Trans functions were not altered from stock as Tim said Darrin takes care of all that through the valve body when he builds them. What is happening is the car is not shifting out of second gear sometimes while driving in town (around thirty). When normally if the OD is left on it will shift to third and into OD. Checked MLPS alignment tonight and is a little better I think but still not as it should be. The car shifts fine once you accelerate out of town. Anyone have any ideas? I've looked through a crap ton of posts with no luck on this. Thanks in advance for your help.
