I Have A 1993 Nissan 4x4 Se V6 King Cab With Automatic Transmission.

For whatever reason, some times when I crank the truck up, it runs just like a dream. Other times, however, my truck starts out in second gear, & remains in second gear. When it's acting up, it will not shift out of second gear. If I drop it manually to first, it seems to start out in first, & will shift up manually into second gear, but will not go any further than that. Even if I shift it into drive and overdrive. It stays in second gear. It starts out in second gear. It remains stuck in second gear. I can park it and crank it the following day, & there's a good chance it will run just fine. Maybe not, but often it does. No check engine light has been on. No problems with the transmission fluid. It looked fine. I ran some sea foam transmission stuff through there, & maybe that will get it fixed, but I can't figure out why it does this only sometimes. Any advice or help would be greatly appreciated. Thanks
