HELP! 94 F 150 Won't Go Into 2nd Gear

[GreyCat]

Hi. I'm new to posting, but have been lurking here for a while. Lots of good advice on this forum.
My problem is that my tranny suddenly decided not to go into second gear. I can get it there manually, but it won't go beyond that point. The overdrive light is flashing OFF on the shift lever and the Check Engine light comes on intermittently.
The truck was recently given to me by my brother who coddled it from the day it bought it in 1995. Last week we put in a new battery, computer, shackle mounts and leaf springs. Prior to that the truck sat idle for at least six months. When we started it a few weeks ago, we noticed that a squirrel had chewed through the fuel line. We replaced that. Is there anything else in that general area that could have been damaged by one of those tree rats?
I'd appreciate any feedback! Thanks.

I don't recall if the PCM controls the gears on that model year vehicle or not, but the fact that manually shifting from 1st to 2nf works, make me think it does.

Squirrel like to chew on wiring. Look carefully under the hood and around the transmission. (My brother-in-law had a car in his driveway for about a month. Squirrels mad a nest that then caught on fire when he started it. Luckily very little damage !)

If you can get it to a large auto parts store they can pull the Diagnostic Trouble Codes and maybe they will tell you something.

Most parts stores don't have a scanner capable of pulling transmission codes from an OBD1 vehicle. Usually that requires a higher quality scanner or a trip to a transmission specialist.

Most stores don't have one have a an obd1 scanner If The od light is flashing you have a problem and like others said you have to go to a specialist for a scan, I took my F-250 for a scan and they charged me 95.00 an hour.
