I have a built Jasper 4r100 tranny. Fixing to go on a 1200 mile trip towing around 7k lbs. I would like to service my trans even though it only has about 38k on it. My buddy works up at ford and says they usually do a flush with mercon V. So i did some research on that fluid and read quite a bit of negative stuff about it. Does any one have any recommendations? :fordoval::fordoval::fordoval:

Typo on my end. I heard negatives about only doing partial flushes. ie not draining all the fluid and mixing mercon with mercon v. Any recommendation on how to DIY. My buddy at Ford is slammed with work and cant work me in.

Well guys, I did the tranny service today. When I dropped the pan, i found pieces of the planetary gear washer stuck to the magnet. Took it by my buddy Ziggy down at his tranny shop. He told me to go park it before I get stranded. He told me I was driving a ticking time bomb. Looks like its tranny time. Anyone have any suggestions??

Get a bts and forget about it.

As good as BTS is, there are a lot more tranny builders out there that can also build the 4R100. It's not like it is a brand new piece of magical machinery.

You can get a well built 4R100 from lots of local builders. Probably will not get the same after the sell service, but sometimes you can not afford the down time when your daily driver is broken.

^I agree. the biggest weak spot of the 4r's and the e4's is the TC, VB and cooler. Fix those, and you can handle some pretty darn decent power. No 600hp+, but I'd imagine below that you'd be fine.

Well the tranny is 3 months out of warranty. After some ass chewing Jasper agreed upon sending me a new one free of charge. It will be delivered tomorrow. So tonight the tranny will be pulled. And vaca will no longer be postponed. Will post pics later.
