Strange F1 Problem on my last drive. Looking for some input from others that may have experienced a similar issue or issues. 2001 360 F1 spider. Last generation(2004?) TCU. New clutch with 3k miles after install. 30k on car. Sunday eve took car for a short drive. Warmed up prior to starting off. 360 still cold so short shifts until oil temp in range. Noted slow shift 1st to 2nd. Not much notice, F1 does not react well to short shifts. Drove about 5 miles, all normal. Downshifted for a right turn onto side street. Noted the car was still in 4th. No reaction from the paddles. Would not upshift or downshift. Managed to turn around in 4th to head home. Made the mistake of pulling both paddles to neutral. Went to neutral. Gearbox would not shift into gear. Drifted to safe place off road. The Gearbox Failure icon was showing on dash during problem. Let car sit for a couple of minutes. Started, icon still showing. No gears. Called my wife to pick up. After about 10 minutes waiting, started again. No icon. Shifted into gear. Drove home. Car shifted normal. Prior to drive: 3 weeks prior installed Scud ing F1 relay. Prior generation to current product. Drove 3~4 times since. No problems. Relay and gearbox fine. Day before. Checked gearbox fluid. Level unchanged/fine. Changes Noted: F1 pump. Longer to prime. Timed after sitting 3 days. 14+ seconds. 24 hours later 14 seconds. Holds pressure well once primed. Last year noted I could hear the F1 pump while driving. Whining sound when on. Sounds normal in garage. Checked with my autel mini clone. No codes shown. Clone does not appear to operate consistently, Another topic for later. My thoughts: Failure due in part to F1 pump. No red light on Scud ing relay I could see. Probably a good time to replace pump. Looked at the Juri upgraded pump on ebay. Reasonable price. Others experience? Other recommendations based on experience? Sorry for long post! Thanks for any input.
