Hi all,

I have a 90 burb. A few months ago had a bit of an issue where the transmission would take a little while to upshift.

Now she won't get out of first no matter how fast I drive.

I pulled the governor and it looks fine. Fluid is where it should be. TV cable is properly adjusted.

Any thoughts? Tranny is about 4-5 years old.

Does that trans have a vacuum modulator on it?
