Coincidence?

[mark corbitt]

So, i just replaced my radiator and i have an automatic transmission which shifted fine before. I had to order a fitting because one cracked during removal, and the auto transmission lines to the radiator were "open" to air for a couple of days. I got the new radiator in fine with no leaks, but when i test drove it, the tranny does not want to shift out of first gear, and i don't seem to have second or third. I have 1st, reverse neutral . Is this a coincidence or......?

Have you confirmed trans fluid level is correct?

Did you refill the trans fluid afterwards?  The radiator holds more trans fluid than you'd think.  And if your trans was already low, it could now be low enough it's not working properly.

Fluid level is good,

Unplug the trans computer and drive it like a manual.  The computer will be located under the dash to the right in the driver's footwell.  It's a metal box that says Aisin on it. 

 

You'll have 1st, 3rd, and 4th (D).  If it drives fine in all gears, then it's an electrical issue.  If you still have problems with the computer unplugged, then it's mechanical.
