Thanks! I will do that! I live in Cortez, Colorado.

Has anyone successfully altered their Mazda 3 from an automatic to an manual? If so, how much did it cost? The tranny needs replaced so just thought I would ask around. Any and all info, opinions are welcomed!

Hi y'all!!! Has anyone successfully converted their Mazda 3 from an automatic to a manual? And if so how much did it cost you? Do you regret it? Any info is greatly appreciated!!

Yes it is! Thank you! I've seen prices range from $16 to $150...which would be best to get for (Part No: FN01-21-550 )

Can someone tell me how to replace the speed sensor and where it's located in my Mazda 3 please!

Has anyone ever had their ecu reprogrammed or repaired from Klein Bottle Computer? They have a website but I can't tell if it's a legit company.

I totally agree. I just don't know where to go from here. Soleniods and wiring harness have been changed..there's no transmission fluid leak..tried to reset ecu to get it out of fail safe mode. But I still only have 1st and 3rd gear. Anymore suggestions??

I think I might need to replace the ECU in my 2007 Mazda 3. If I buy a used one would I still need to have it programmed by a dealer? Or is it a plug-n-pay kind of thing?

Then would it do any good just to replace the entire ECU?

Where is the TCM located? And how much would you think to replace it?

I appreciate your insight! I checked and no leak. Any opinions and advice is welcomed and appreciated!! New problem just arose...when shifting from park to reverse when the car is cold it doesn't go into reverse. It's like it's stuck in neutral.

Yes, the transmission fluid was changed when the new solenoids were replaced. Also the wiring harness was replaced as well. Could it be that it's stuck in "safe mode" and if so how do you go about resetting it? Would it be wise to have a transmission flush and have the speed sensor replaced?

I have a 2007 Mazda 3s automatic transmission and it has about 78,000 miles on it. The check engine light and the at light are on. I had it checked for a code and it gave me p0757. I've replaced all the solenoids. I can only go up to third gear! Has anyone else had this problem??
