Remanufactured 4R100

[Hank]

Just purchased an '01 (102,000 mi.) with a Ford remanufactured tranny (tag on side). Dealer told me that it was just installed. I contacted the service center and was told that they installed a torque converter and that the reman. tranny was in when they got it.
Issue: The Ford required inline filter appears, to me, to be in the wrong line. It was cut into the rubber section of the line from the tranny to the passenger side of the cooler. I have read that it should be on the return line (driver side) between the first cooler (radiator type) and the second one (air) to catch metal that may have been trapped in the cooler. I dropped by another Ford dealer Friday and purchased the Trans Filter Kit with the intention of installing it myself.
I decided to try to confirm the 3 year-75,000 mi. warrranty Ford supposedly offers with remans. and have thought twice about messing with it before I consult with Ford.
Does anybody know how to verify warranty info. with tag numbers in hand? Ford dealer gave me a phone number to try Monday.
If I'm right, will two filters be OK or should I have the line repaired? It's leaking too. Can't tighten the clamps any more.

Sorry for the length of this. Just couldn't say it with any less words.
I love this site. I'm a newbie and all I know about PSs is what I have learned from you guys. Thanks!

Hank I wish I could help you with your question, but I'm clueless. Least I can do is give you a free bump to the top and say welcome to the site. Good luck with your problem and hopefully a tech will be along shortly to help ya out!

another bump!

Thanks for the bumps. I have learned a great deal from this site so far but guess the tranny question was just too tuff. Ford Motor has indicated to me that within a month or so any dealership should be able to run the numbers found on the tranny and get a "history". I plan to have a tranny shop install the filter I purchased on the proper line and give it a good going over. A filter coming and going hopefully won't hurt anything...'cause I sure don't know if none of your members don't!

For Magnefine filter installation instructions, see:
Magnefine--Magnefine Filter Installation Instructions

Since your vehicle has had transmission problems, the filter should be installed in the return line from the cooler to the transmission. The return line is the metal line running to the BACK of the transmission. This metal line hooks to a rubber hose that runs around the right side of the radiator to the transmission cooler. Install the filter in this rubber line.

The filter is directional, so make sure that the filter is installed with the arrow on the side of the filter pointed in the right direction (in this case, toward the transmission).

I appreciate your help. I had pretty much decided that I needed to do what you suggested. I just wasn't sure if "double filtering" (supply and return) would cause any problems. I am going to go ahead and have a transmission specialist (not Ford) inspect/service it and install the filter I bought in the return line. The kit came with the connections to cut it into the metal line if I want to. I will let the shop decide. I may go ahead and have the supply line repaired at a hydraulic hose shop and put it back to stock. It leaks and nothing I have done seems to correct it.
Do you have any idea of how I can take the bar code information from the rebuilt tranny and determine the "history"? Date? Mileage? etc.? Two different dealers have told me that they can register one but not trace one. So how do they determine that a rebuilt tranny is still under warranty? Duhhhh?
Thanks for your help.
