Mazda Transmissions

MAZDA JF506E 5spd Transmission

Complaint:
Slipping, chuter or no reverse gear.

Cause:
 We have seen the reverse piston in the transmission crack.

Correction:
As they appear to be more commonly failing in recent times, there is aftermarket pistons available. Good news is they have been upgraded to last a bit more then the stock type.

Result: Once the updated pistons are installed, you shouldn’t have any relevant complaints.

Note: We have come across other causes as to why reverse gear is failing as well. As the piston is a common cause we have seen solenoids, valve body, wiring harness give a similar complaint. We will need to inspect and diagnose the vehicle on a job by job basis.

MAZDA JF506E 5spd Transmission

Complaint:
How do I check the transmission oil level on this thing.

Cause:
I am not sure what they were thinking at the time 

Correction:
 To check the oil level, have the car idling in park and undo the allen key type bolt located under your transmission.
(don’t worry you wont loose all the oil, inside the case directly above the allen key bolt is a long tube and goes as far as the desired correct oil level)

If the fluid trickles/ spills out then there is enough fluid in your trans. If drops / or no fluid comes out then you will need to add some fluid.

To fill / add fluid, this can be achieved from the tiny fill pipe located directly above your transmissions pan. ( the pan is located on side of trans and facing the radiator / front of car) just pop off the rubber grommet acting as a blocker over your filler pipe.

Result:
You can now check the level without having to take it to your nearest repairer.

Note: Use genuine correct fluid on these things. Not cheap.
