I took my 91 XJ in a couple weeks back to have a blown brake line from
the master cyclinder to the rear axle replaced. Ever since I've got
the truck back it doesn't shift right. It won't shift out of first
until the tach hits 3K. Also it won't shift into overdrive until I'm
doing over 72mph. It never did this before and it's getting really
annoying. Any ideas what it could be? Also I hear a loud whistle when
I put my foot into the gas, like a turbo sound.

thanks

Bob

First thing I would do is to look in all the areas where work was
performed....essentially follow the brake line from front to back....
and look around the areas to see if something (vacuum line, electrical
connection, etc.) was left disconnected. I would suspect something was
left or got disconnected (vac line or electrical connection) around
the master cylinder area. Check the throtte body and make sure all the
connectors are in place. Also look for any signs of contamination due
to brake fluid (soaked electrical connectors or rubber hoses); brake
fluid can be a strong solvent (it will take paint off). Address any of
these areas as you find them. The other input to the transmission is
the throttle valve cable (TV cable); it is the black cable connected
to the throttle body and runs back and down to the tranny. Check its
adjustment: push the release button/lever and slide the adjuster all
the way out (pull it towards the passenger side). Next, get in and
floor the gas pedal; you;ll hear the cable adjuster ratchet as the
adjustment is made. You're done with that. Might as well check the
fluid level of the transmission while you're at it.
