Twisted said:If you are out of warranty. See what the parts from the list on this thread will cost, then check with the dealership to get an estimate on the labor. See how high it is and decide if you want to **** the 3650 and try something else or maybe a different car.

bbalzer said:I have a 2003 GT. Took it in to the local dealer in western Okla. today to see what they would do about the shiftinf issue from 1st to 2nd and 2nd to 3rd. Head mechanic called the Ford hotline and they told him to order the following parts:
3r3z*7124
3r3z*7102
3r3z*7107
3r3z*7230
1r3z*7109 they did not include 1r3z*7H150 as some of the posts did.
The Hotline told him that there WOULD be a TSB issued. They are trying to roundup 500 complete parts kits before issueing the TSB. My parts are on "expediate" order and should be installed in the next several days.
Mustang5L5 said:What exactly are these parts? What are the technical names. I have been studying a T-3650 service manual and am curious to see what they are replacing. From the looks of things, the shift rail system is overly complicated. The synchros themselves look no different then the T-5/T-45 synchros but the setup the T-3650 used to shift them seems over-complicated to me with the use of seperate LONG shift rails. The t-5 setup seems so simple with it's single main rain and 5-R lever. I'm curious to see if they are replacing the rail system or the synchros themselves. I'm also trying to score a local broken T-3650 to pull apart and mess around with myself. Might come in handy learning how to rebuild these. I am already pretty proficient rebuilding the T-5
Also, The ford hotline said they were waiting for 500 kits? Is that nationwide? I would think most everyone would want this done. My T-3650 is tolerable with only a 1-2 notchy feeling, but i would plan on having the work done before the warranty expires anyway. I want to make sure nothing happens in the future

SilverGTV8 said:I belive the actual cause of the problem is that the material they chose for 2-3 syncro is to soft and the tranny eats it up, and that is what they are changing. I think they chose brass and it was to soft, I think the new syncro is bronze
gtrackd02 said:i was told that both the 1-2 and 3-4 were being replaced, and also a bunch of other parts that i did not get an explanation for were being replaced as well..
He sounded pretty sure of himself on the syncro replacment though..
But who knows how credible a ford dealership's service manager is...
Mustang5L5 said:Not to be disrespectful by correcting you, but in the T-3650, it's 1-2 synchro, 3-4 sycnrho, 5th sycnro and reverse synchro.
WHat we need is a TSB that replaced both the 1-2 synchro and the 3-4 synchro.
Twisted said:I don't think the syncros are failing here. They are just too small to speed up the beefy 2/3 cluster. The fix kit has thinner gears (read less mass) and I am not sure on the syncros if they are larger or just a different material. Anyways, my car still has the hard 2/3 when cold, but no grinding yet. It is summer though.
