1995 F150 XLT 5.0 E4OD auto(Ithink).

Today while driving my check engine light started going berserk, and not 10 minutes later, my truck seemed to lose 2nd and 1st gears unless I manually shifted into them... When I kept it in drive, the truck would seem like it was bogging down/would not accelerate until my foot was on the floor and then it worked okay. This only happens up until 45 mph after that it's no problem, it shifts into 3rd and up perfectly fine. I have no idea what this is from. The trans fluid is right, it's clean, I'm hoping I'm not losing the 2 gears.

Also prior to this happening, since I have owned the truck, it shifts hard from 1st to 2nd and 2nd to third, it gives a real jolt, not sure if theres some kind of link between that and this new problem, but its been that way since I've own the truck ~3 years or so...

Someone please help, I don't have the cash to drop on a new(er) trans so I'm hoping its something small

 

I'm not a tranny man but pull the codes from the computer atleast we can see what the tranny was telling the computer.

 

Check your O2 sensors. With the pedal on the floor, the computer reverts to open loop operation and doesn't read these sensors. I would hazard a guess that among the codes you pull will be random multiple misfire and O2 sensor (one or both) not switching.

 

I took it into a shop cause the brake lines all decided to crap out at the same time... Coincidence, I hope... Well the shop said that my cat converter is trash, so would you guys all believe that might have caused the issue, the shop said they found nothing wrong with the trans

 

I will run the codes tomorrow when I've got some time and post them up
