Transmission or transfer case

I am assuming this is a tranmission issue and not TC, but have to ask. Do automatic transmissions have synchornizers? I have 2.5L automatic and when it shifts the engine revs real high and you have to let off the gas for it to shift into the next higher gear.

No that's a trans shifting issue. Something is wrong. Someone will chime in with the fix

You could have low transmission fluid, you may also need to adjust the kickdown lever. Or your transmission may just be going out.

What you are experiencing is worn clutches or bad internal seals in the transmission. An old car dealer trick is to add 1/2 pint of brake fluid to the tranny fluid it will swell the internal seals and may help for a while. Checking the fluid is always the first thing you do. If the kickdown linkage is intact I doubt its the culprit it generally just holds the shift and when it does shift it bangs into gear.

200,000 + miles.
Fluids changed less than a month ago.
Lucas Oil - Transmission conditioner was added.
When the transmission is in gear, there is no slippage. it only happens when shifting.
I have noticed that on a slow speed increase, as I approach 40 mph, if I let off the gas, it will drop the rpms from 3k to 1.5k and then shift into 3rd without issue.

There is an adjustment procedure for the bands that may help.

Take it to a shop have them check it out.

If you feel slippage ( high revs but jeep doesn't accelerate, something like when you put manual transmission into neutral while car is moving and press throttle pedal) , check bands (both front and rear), and TV cable.. Which fluid did you use for replacement?

If there is no slippage ( only delayed shifts, like when you press half throttle and car accelerates but gets to 3-4k rpm and wont shift until you release throttle) then there is something wrong within valve body in transmission (some valves are clogged, governor valve is clogged ) or throttle valve is misadjusted (you need to adjust TV cable for this). Does this happen to you in every gear?

It seems to be only when shifting from 2nd to 3rd.

But do you feel slippage then, or it just revs too much? If it only revs too much its probably some sticky valve... I had exactly the same problem, but in my case, when it shifts, second time it will shift much sooner. Until i turn off jeep.
