Transmission shifting funny after valve cover gasket replacement

[FoneRunner]

I replaced my valve cover gaskets last weekend to try to eliminate an oil leak...pretty simple job once I got into it. Today was my first day driving it since the job and there is now a pronounced delay between first and second gear on my AT when I take off quickly. Not so much when I take off slowly though....checked the fluid and it's fine right color and quantity. Question is, is there anything I could have done inside the engine compartment that could cause that sympton? Vacuum hose or something? If it were a manual transmission I would say it feels like I'm riding the clutch...for those who know what that feels like...Thanks!

There are two cables on the front mounted to the plenum, both connected to the throttle, one is connected to the accelerator pedal and the other is connected to the transmission. Check both.

Thanks! There's 3 cables connected to the throttle body...one goes to the gas pedal, one goes to a box in the engine compartment, and I guess the other one goes to the tranny...any idea which way to adjust it? I must have messed it up when I disconnected it, huh?

The one that goes to the box in the engine compartment is the cruise control.

Of the two cables, the one closest to you when you stand in front of the car with the hood up goes to the accelerator pedal. Use a 14mm wrench to loosen the nuts to adjust. Proper adjustment is to make sure it is taut but doesn't open the throttle. Moving to the left gives it slack, moving it to the right makes it taut.

The cable that is behind it is to the tranny. Adjust it the same way, but this time there is what looks like a real small nut on the wire. This nut is only supposed to extend 0mm-1mm beyond the rubber boot on the cable. Adjust it so that it is between 0mm-1mm.

Adjusting the cruise control is also the same, but I have found that it is more trial and error. Making it loose or taut affects the CC when it engages. I've found that if it is taut, when you engage the CC, it may actually cause the motor to throttle up. Only after some tweaking did I find a setting where when the CC engages, it doesn't do that.

BTW, you can download the FSM for the 4R here: http://www.ncttora.com/fsm/ instead of blowing your hard earned cash on a book.

I'm gonna go ajust it right now! I'll let you know how it works out since I'll be putting another couple of hundred miles on the truck today!

I am happy to pronounce it fixed! Thanks to the excellent advice in this thread my transmission now shifts just fine again....not that I'll be able to explore any lake bottoms or anything but mountain tops better beware!!:trophy:
