Question:

What is a 4 valve-pump transmission?

I need to find out if my mechanic is giving me the run around. I have a 2002 Isuzu Axiom. Apparently, it has a 4 valve pump transmission, this particular year being the only year that has one. This part needs to be replaced and supposedly is very difficult to find and can be expensive. I would like to know what this part is, its usual price and if it is truly that hard to find?

Answer:

If you need to be so synical call the auto parts store or dealer
its a 4L30 transmission and the mechanic isn't lying. they had problems. if regular transmission shop he should of been able to get the updated assembly. if a regular garage just have him yahoo/google after market transmission suppliers to se if they have the pump
whenever you have issues like this always get a 2nd opinion your insurance agent always wants 3 estimates
