Transmission is slipping when cold and gradually works better when gets warm. Thinking about adding some transmission conditioner. Should I remove and replace transmission fluid first then conditioner or just add conditioner. Thoughts?

You have a 4R44E automatic in a 2000 2.5l Ranger
Expected miles before clutches and bands wear out is 250k, but really depends on service and usage(heat)

Look at the fluid on the dipstick, darker red means its overheating so yes change it and the filter

"Trans fix" type fluids help to seal gasket and seal leaks, also help clutches and bands to grip better
But it doesn't "fix" anything but can help to get a few more miles out of an older automatic

Slow to engage Reverse means a pressure issue, which can also cause slipping in forward gears
Trans fix helps to raise the pressure back up

Look at the fluid on the dipstick, darker red means its overheating so yes change it and the filter - The fluid color is darker red.

"Trans fix" type fluids help to seal gasket and seal leaks, also help clutches and bands to grip better , But it doesn't "fix" anything but can help to get a few more miles out of an older automatic - Does the trans fix hasten the total breakdown or just help it work better until the inevitable total breakdown?

Slow to engage Reverse means a pressure issue, which can also cause slipping in forward gears
Trans fix helps to raise the pressure back up - Exactly what is happening!
Background - a couple years back the Ranger was my daily driver until I saw the heavy corrosion on the frame. Aggressive rust/corrosion on the front passenger side where the strut tower/control arm etc... attach and would not be pretty if hit a pothole a higher speeds. Anyways decided to keep on road locally/slower speed etc....

Main question if I add the "Trans Fix" now will it hasten the demise?

Thanks for your information this is very helpful!

Have you checked the fluid level?

Usually when it acts up cold but is fine warm its just low.

If something is cooked its usually the opposite

I don't think Trans Fix will harm anything. It's just a bandaid that kicks the issue down the road. Sooner or later it's going to need fixed and possibly cost more to fix since the needed repair has been delayed.

If you don't have the money to fix it now, Trans Fix will keep you on the road and give you time to save up the money needed to repair or replace the transmission.

I have the money but the Ranger is really a back up vehicle due to the frame being corroded to the point of not on the top of my priority list, but if I can get it back to just local running around that would be a gain. See picture of frame on passenger side where top strut mount. This is why not pressed.2000_FordRanger-passenger_strut_mount.jpg

Follow the directions on the bottle. I suspect it will tell you to pour it in first and then add ATF as needed. You don't want to over fill the transmission.

Will do, and thanks for the information. I will add the Trans fix first then the ATF and not overfill.
