4 speed acting like a 5 speed.

'01 f250 7.3 an it shifts fine until during 2nd gear it acts like it shifts again but it's not. Then 3rd and 4th gear are just fine. TC? Solenoid? It's real weird though.

It's not weird, it't normal. What you are feeling is the TC locking up.

[AOx4]

Yes, that is just the TC locking.

I had that same question when I bought my truck too! Just the TC locking up.

[Frankf250]

TC shouldn't be locking in 2nd? Usually only 4 and 5 do that

It's never felt this weird though since we've had it (155k when bought now 267k). It feels like its surging. Does it mean its slipping?

You should be able to tell when it's not locked or slipping. Just blip the throttle a bit while driving and you will see the tach climb faster than the speedometer. You could also hook it up to a code reader and check the amount of slippage. If it's the original transmission at 267k, you have probably set a new record and should plan on getting it rebuilt.

Maybe Santa will bring me a bts this year. Lol

Over-rated for 400hp or less.
