When I first start up my truck in the morning it feels extremely sluggish. It doesn’t want to go until its fully warmed up. The RPM’s just kind of rise up like the tranny is slipping I guess. As soon as it warms up it gets way better but still feels more sluggish than a couple months ago. I’m trying to figure out if it’s the engine deciding to be old or if it’s the tranny going. I wish there was a better way to determine this. Any ideas?

 

Tranny filter change and tighten up your bands...

 

Hmmm...any good write ups??

 

You might try resetting the PCM buy pulling the fuse for about 30 minutes.

 

I would do a pan drop and a fluid flush. Sounds like you have some build-up in the solenoid valves in the tranny.
