It just stall when i'm changing geares from any gear 1,2,3,4 or to 5

Before you take the vehicle to any mechanic, check the vacuum line that runs between your brake booster & fuel injection aluminum dome.  The computer will choke the vehicle trying to compensate for a leaking vacuum hose... that's about $60 if you do it yourself!

I am "Master Technician" and This is my area of expertise.I perform engine computer diagnostics and all other imaginable electronic problems.15 years of experience,5 years of technical school.Those are my credentials so you know, who you get advice from.Now going back to your car problem.First, check engine and trany fault codes if there are any, write them down and transfer it to me. If there is nothing, then we got intermittent problem which is a B..CH. 1->{try to check "ECM"(engine control module) for water damage,common problem}. 2->{check ignition module,ignition coil for voltage and resistance,could be too low or too high.}. 3->{check crankshaft sensor resistance}. 4->(check fuel pressure}. 5->{check catalytic converter for exhaust flow,if it isn't clogged.}. 6->{check with scanner engine's and trany's "data stream" for any parameters out of spec.}. Last but not least 7->{check your trany's clutch for wear,trany fluid condition & level.}
I can't tell you exactly what's the problem without road test your car and feeling car behavior while stalling. My best bet is (crankshaft sensor) or (trany & clutch).Write me back what you'll find, So I can give you more pro advice. Sincerely JAYREE.
