stuck in first gear

[jimboborino]

i have a 83 excalibur motorhome with a 454 chevy and a turbo 400 transmission, i rebuilt the transmission myself with help from internet i had to do it twice, so i'm confident that it's done right,everything on the inside is new and everything on the outside is new, so i'm kinda out of things to repair or fix any help that you fine folks out their i would be greatly in your debt for any help, i've been trying to get the tags i keep having walls appear in my path. thanks Jim &Cindy:confused

I had that EXACT problem with a Chevy van w/350...it was a small plastic gear accessible on the outside of the xmission...$5 and I was on my way...hope it's that simple.

Do you have reverse gear? Could you possibly have a shift linkage problem, either with the external shift linkage, or internally?

Also check to make sure you have good Source of vacuum to the Vacuum Modulator and make sure to check the mod as well for proper working!

first thing i would do is unplug the kickdown switch on the side, if activated it will not upshift. next check governor see if it is free. remove governor (4 bolt cover on side) hold up by gear and push in weights, valve inside should move. good luck
