Transmission not wanting to shift?

[1995E]

I've been experiencing some transmission issues lately with the Explorer not wanting to upshift. It's worse when I have the A/C on.

I don't know if it's due to the higher temperatures or anything but I'm just trying to cruise along at 35 and when the speed limit goes to 45 and after reaching a stop, I am accelerating, and it upshifts at 2,000 RPM to second gear, then it was climbing all the way to 4,000 RPM. I had to put it in Manual mode and made it upshift. I haven't had transmission bumps in a while but the transmission bumps returned again, especially while climbing a hill.

With A/C it's worse, the acceleration is sluggish and the RPMs hold up until 5,000 RPMs before it wants to upshift. This concerns me because it's a waste of gas, and it's going to make the engine age faster.

Recently, I've been having vibrations in the pedal when those incidents occured, I don't know if these are connected.

Anyone else experiencing this issue? I would like to think it's normal but this really bothers me.

I assume that you are not racing away from a stop. If this is new, then I would have it checked out. I haven't really paid attention to what the shift point range is so I can't help you there but I would think 4 and 5k is a bit high.
I don't notice any difference in mine whether the A/C is on or not.

Yeah, I'm not punching the throttle at all, I press it ever so slightly to go only to the max of 2,000 RPM. I changed my driving habits a lot and I've recently hit 17.1+ MPG city compared to last year's 15 MPG. Used to when I would press the throttle harder, I'd reach 2,500 - 3,000 RPM.

I am thinking this is related to the transmission bump TSB because in the description, it says sluggish acceleration and I've had times where the bumps were big but the amount of bumping have slowed down a lot. When I brought it to my dealer, I couldn't replicate the bumping issue last year so the TSB wasn't done.

Anyone had similar issues, then got the TSB done to where it fixed the problem?

Okay, I got a chance to check mine today. Under moderate acceleration, the first shift was at about 2000 RPM, the second at 2500 RPM and the rest were all around 2000 -2200 RPM.
That was fairly consistent as well.
