WJ Transmission Slipping after Radiator Work

I have a 2001 Grand Cherokee Laredo, 4.0. My Radiator was leaking and I took it to a shop and they removed the entire radiator, replaced the radiator tank (which is what was leaking), flushed the entire system, and replaced a couple of hoses. No more leak.

BUT- since then my transmission is slipping between 1-2, and 2-3, mostly. Also, it seems a little sluggish. I tried to check my transmission fluid level - couldn't really get an accurate reading, but put in about 1/2 quart of fluid. After about a day or 2 it seemed to be slipping a little less, but still slipping and still a little sluggish (I changed fluid and filter about a year ago.)

Any suggestions??

What do you mean you "couldn't get an accurate reading"??? Check the fluid and make sure it is full. You find yourself paying the bill for a baked tranny you will be sure to get it checked accurately. I would not have left the shop without getting an accurate reading on the dipstick. It could be lower than a quart. Some "techs" just let it drain while they do their work and estimate how much leaked down. Run the engine, shift it through the gears with foot on brake. Put it back in PARK, get under the hood and pull the dipstick, wipe it off, stick in there and pull it back out and read it ACCURATELY. Top off fluid as needed.

For the 42 trans it needs to be in neutral.

The reason the dipstick has 'markings' on it is so that you CAN fill to the proper and accurate level. Some times I spend 15 or 20 minutes getting the correct amount of fluid in the trans. Only pour a small bit in at a time, as you DO NOT WANT TO OVERFILL! With engine running, shift through all the gears, then leave it in neutral. Pull dipstick and wipe it dry. Insert dipstick, and keep wiping it dry until you get an accurate reading on the bottom, so you are seeing the actual level of fluid. If you add fluid, repeat the process. If you overfill, you will have to either drain or suction out the excess amount of fluid. That is why you only add a small bit at a time.

As mentioned, overfill or underfill could result in you buying a new transmission. This is not the windshield reservoir, that you are just pouring a random amout of fluid into.
