Hi! My car is a Suzuki x-90 1997, 4wd, auto transmission... since about 7 months, my transmission begins to shift from 1st to 2nd at
4500 or 5000 RPM instead as 2500 as usual at the first start when it's cold almost every morning. Since the weather is warmer, it occurs only once in a while. Transmission and dealer's mechanic are not able to find what is the problem. It seems that one of the sensors is faulty but we don't know wich one. One of the solution I have is to change the transmission (around $1000.00 for a used one and $3,500 for a new one)) and they are not sure that it will solve the problem, or get all of the sensors checked one by one (begins at $600.00 and don't know where it stopped) and the last one is to replaced all sensors but some of them goes up to $1,500.... I want to have it fixed but I dont't want to pay for nothing anymore. It already cost me over $700. to change nothing. So if someone once have the same problem and have the solution.
Thanks!

P.S.: coolen sensor has been changed as well as trans fluid. Suzuki don't produce any code for that car cause they produced it only 3 years... and they never have that kind of problem before.
