Hi Scotty, I live in Australia and have a 2002 Jaguar X-Type 3.0L AWD automatic. In 2018 while I was researching changing the transmission fluid the transmission started slipping. At around 60000 miles (100000 km here) I thought I was ahead of the game but sadly I was mistaken. Could a Jatco JF506E expect to have problems after 16 years with only limited mileage? I used Castrol Transmax Multi Vehicle fully synthetic ATF, drain and measure - refill with same volume - run for 14 seconds - drain and measure - etc. (The rest of the story is below) Since then I was advised there is a difference between the fluid I used and Castrol Transmax Import Multivehicle fully synthetic ATF - this one isn’t available in Australia. What could you expect to experience using the former named fluid instead of the latter? I had to get the transmission professionally rebuilt, everything new including solenoids, GSR kit, piston kit, and the torque converter was rebuilt. The repairer advised that they used the same fluid I used (non Import version). What would cause this failure in a low mileage 16 year old X-Type? The filter in this transmission cannot be renewed without separating the case, how often should the ATF be renewed to extend the life of the transmission as much as possible? The rebuild was thorough, I believe, and not cheap (A$6000). The non Import fluid is about $250 for 21 quarts (20 litres), not even Amazon will ship the Import variety to Australia.

After replacing the ATF the car seemed to do everything right around town and at city speeds (60km/hr - 40m/hr). Heading out of town in a 70km/hr - 45m/hr zone I started going up a fairly steep hill and as the gearbox changed down from 5th to 4th the gearbox fault came up on the dash and it was as if I had selected neutral in a manual box. It slipped for a bit then I went over the hill and rolled down the other side. Turning off the highway and slowing down the gearbox picked a lower gear and we were driving again still with the gearbox fault showing. I drove back into and across town to add fuel and when I got out I could detect a burnt smell. I got home alright but decided not to use the car until I had changed the transfer case fluid. I changed the transfer case fluid and went for a test drive. Again everything around town was fine changing up and down through the gears relatively smoothly until I came to the same hill and experienced the same result. Coming straight home instead of going for fuel I encoutered a few more hills and every one was like trying to drive in neutral. Engine revs would pick up and just keep climbing as the throttle was applied but no drive at all, like pushing in the clutch in a manual and hitting the loud pedal. I found if I selected third with the J gate shifter it would engage and cycle through 4th and 5th when D was selected, but each hill ascent produced the same now predictable result. Returning home saw the return of the burnt smell. The only code thrown was P1647 (cheap OBDII Bluetooth connector), along with the gearbox fault on the dash along with the amber light.

Yes, that plus jags are endless money pits. You're crazy putting money into the pit any further. Car here in the US is worth basically nothing at that state. I see guys buying em all the time for 900 bucks or less

JatCo. Worst POJ transmission on the planet. The fact that between Scotty and me, we own FIVE Toyotas total must tell you something.
