NEW CF w/ trans problems...

International Tech · May 29, 2006

Last week i had a new 07 CF w/ 4200 miles on the clock towed in. Customer complaint was that it wouldnt move in any gear all of a sudden. I install the driveshaft and start her up, put her in gear, and away we went. After 80 yes 80! miles of test driving i couldnt get the darn thing to act up. NO CODES ANYWHERE! Call tech service and talked to one of our 2 CF gurus and told them the complaint. They knew exactly the problem and sent me a new valve body. The valve body hasnt arrived yet. I was also told at that time this is a common complaint and that we are instructed to phone in EVERY CF that comes in for ANY work (besides maintenance). Thanks God for International. Without then i would be out of a job.

These 5R110W Torqshift transmissions can do some erratic and strange things. They are completely electronically controlled by the use of the solenoids in the solenoid body. The solenoids rarely fail on their own but they are very sensitive to debris that will cause them to stick. When you replace the solenoid body make a very thorough inspection of the pan. if you find anything that looks like this...

...then you will definitely want to find the source. As always some black goop around the magnet in the pan is okay and is quite normal. It's the large deposits of metal in the pan that signal a developing mechanical failure. This picture is from the 04B24 recall article.

usually this trans loses epc pressure due to contamnination . it will free up and then work fine . metal is usually from case where the planetray gearset rides . or snap ring but snap ring generally loses reverese not just forward
