Default Help Transmission Issues Help

Today I jumped on interstate 40 and was merging into traffic. My car shifted into second gear and never would come out. I was running down the interstate at 5k rpm until i could jump right back off the interstate. I turned the car off and turned it back on. It went back on with no issues and shifted fine. What issue could I have?

I just moved to Raleigh, NC and I don't have a mechanic that I know. I am hesitant to take it to the dealership. I don't want to get raked over the coals and have a hefty unnecessary repair.

What could the potential problem be? And does anyone here know a good mechanic in Raleigh, NC?

Thank you in advance.

04 is the "sealed tranny."

Sounds like a valve body issue or electrical issue in that scenario.

Chances are it's just a one off freak valve body bock and has cleared itself.

Don't manually shift it... It's not a race car...

2005 with 110 miles - Your AT is sealed uint, no dipstick. If it were my car I'd have my ATF replaced by a lexus or toyota dealer. They can hook it up to a machine that completely replaces all the fluid but does not do a power flush (power flush can sometimes cause problems). Lexus says ATF is sealed and "lifetime" ATF fluid - I think that is BS unless you want to replace worn out AT at approx 140-200k miles on average. I intend to replace ATF fluid on my 06 LS every 50 k miles.
