On my 98 that tube isnt there the line runs down to the condenser mounted pretty much below the rad behind the bumper.

I will be doing rear brakes this week. Hopefully it is just the brakes not something more. I hope to get to the various trans stuff the week after, that would be the cooler, gauge, and seal at the back of the trans where the drive shaft connects up.

I want to install a trans cooler. My existing radiator has a full width A/C cooler in front of the radiator. Are there problems having THREE coolers in a row in the stack? (radiator + A/C + Trans).

I have not heard of anyone running hotter with a trans cooler in front. As long as your engine clutch fan is working properly you won't see any difference in engine temps.

I've got my tranny cooler mounted... Removing the grill was very easy once I found the correct tool. All I need to do tonight is run the hoses, check for leaks and top off the trans fluid. Let me know what you think, picture below.

And the reason I stopped here, besides being late... I am having A LOT of trouble getting the upper return line unscrewed from the radiator. I'm afraid I am going to break something if I try any harder. Should I just hit it with PB blaster and give it a minute? Any other suggestions?

EDIT: I think I mounted it a tad too high... Worth re-working? Or should I be fine?

Looks good so far. If the grill fits I would leave it.

As for the fitting in the radiator, hit it with PB Blaster and slowly work it back and forth. Be sure to hold the big nut on the radiator tank to keep it from turning and breaking. If you want to make more room, pull back the plastic clip cover and remove the small wire clip under it as in the following pic. You can then pull the line out of the fitting. It is O-ring sealed. You can then get a box end wrench on it so you don't round off the nut.

EDIT...

Got the grill to mount with some utility knife triming to the back... Is this normal? Does everyone elses grill clear the cooler no problem?

So now how much ATF should be added. I think I read somewhere about a quart.

PS. I am not a mechanic at all, the most I had done before this was replace an air filter and windshield wipers...

Drive around a bit so the fluid heats and goes through the cooler, then check your level and top up. The only annoyance is adding fluid in the dip stick tube, you need to wait a while for it all to go in to check the level again or you have the residue all over the dip stick.

It just takes time for it all to run down. Be patient.

No... I would like to put one in eventually, but didn't have the time or funds right now. Knowing I have the trans cooler is good enough for me since the trip was going to happen with or without it. In the end its not a burly trailer, just a 6'x10' enclosed Haulmark loaded with about 8 mountain bikes and camping gear for 4.

No idea if it is normal, but I will have to do some on my Safari's grill. I though I had just enough space, but I don't, and I have the stupid tube from the AC running across the front of my van (mentioned above) or I could get it to fit. As it is, to fit it will take some grill trimming.

Edit:

Thanks to the dremmel, all it well and everything it installed except the trans temp gauge. I think I will need some more wire to get that done.
