Governor cleaner?

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.

brake clean, carb clean, pick your poisen. although the governer should be self cleaning for the most part. tv cable not adjusted can prevent shifts altogether because it can pull the throttle valve all the way in its bore my 84 cougar 5.0 did that often when the retainer bushings wore down the tv rod would pop off also change the fluid may help clean the valve body out
