Governor cleaner

[Dalinkwent]

Hello I've just recently replaced the transmission in my 91 tbird 5.0 HO and it's decided to go AWOL and not shift. It was shifting fine for the first few weeks now it just stays in first. I didn't adjust the TV cable yet which I probably need to do but don't have the tool. but either way the worst that can do is keep it from shifting at high rpm's . I think? I'm pretty sure it's the governor in the trans because I had to cut the tail stock off the end of the transmission( trany came out of 89 linken town car), even though I covered it very well I think some chips of metal may have gotten in there. I was just wondering whats the best thing to clean the governor off with that won't leave any residue be hide that could cause it to stick again. I was thinking carburetor cleaner but I'm not sure.. I just need something to spray it down with to wash w/e might be keeping it from sliding. Thanks for any help.

It may be debris in the valve body, as well.
Try dropping the pan and taking a look. If debris is going around, some should be in the filter and pan.
Its no big deal to remove the valve body and clean it out with brake cleaner, (it evaporates quickly with no residue)
You did put a magnet or two back in the pan, didn't you? Try for 2 or three of those flat magnets, 2-3 inches in dia, and about 1/16 to 1/8 inch thick. They should catch most debris, except for aluminum from the housing.

Am I gonna have to remove all the bores in the valve body and clean them or can I just flush the transmission out with new fluid? and no I didn't put any magnets in the pan. Is that safe to just put the sticky magnets in the pan or should a magnet be welded on? do they make drain plugs that are already magnetized? Thanks for your help any more advice would be appreciated.

They do make magnetized drain plugs for most stuff. Also, doesn't superheating a magnet (as in welding it) demagnetize it?

Dont weld the magnet in; it wil be weakened by the heat of welding. It will stick just fine to the inside of the pan, so long as you have the factory steel pan and not an aftermarket aluminum one.

BTW every new transmission I have ever seen has a magnet in them For some reason, lazy mwechanics throw these magnets away, instrad of cleaning them when they service a transmission.

You would be amazed at how much stuff they will catch,

Magnetic drain plugs are okay, but do not hold as much stuff as a pan magnet becasue the are smaller. Most pans have no plugs unless it has been added or the pan is aftermarket.

As for flushing....you may have to remove the valve body and clean the valves.....but there is lots of tiny parts in the valve body that can fall out or get lost, so it would be nice if you dont have to.

You might be able to dislodge the debris by flushing the pan then running the car and shifting the gear shift through all the gears when stopped and also when moving.
