with 200k miles, while sitting at a stop light surges when my foot is on the break every one once in a while? I was wondering if this was a early sign of my transmission slipping? I am also on the lookout for a pocket-friendly window regulator, it's a 99 model. Kindly help me on this one..

 

surging at idle at a stop is usually not an indication of transmission problems if it was really low on fluid it might slip in and out of gear but it would be more obvious when you took off from a stop that it wasn't in gear.

try to check this Regulator for your ride.
