Hello I just picked up a 2007 l322 and I’m in love with it! It drives and shifts perfectly. My question for you guys is the car has 111,000 miles on the car is it still safe to do a transmission service? Also the transfer case has been replaced in this car and on the receipt for it it states that they needed transmission fluid. So my second question is did they do a transmission service when they replaced the transfer case?

I guess you're asking "did they address that or not?".

The transfer case bolts directly onto the rear of the auto transmission and is a completely separate unit, including fluid wise.

Unless it states specifically on the the paperwork passed to you that the auto transmission and filter WERE replaced you should assume that it was not.

To be on the cautious side I'd read, "...Needed transmission fluid..." as an indication that an oil and filter change is still an outstanding item requiring FURTHER attention or, at best, that the transmission may have been topped off to the correct level [something of a temperature based art].

A filter and 6L of the correct ZF oil is a lot less expensive than a replacement transmission.

Thank you so much I have an appointment scheduled for this week! My initial question though was I know that the friction from the old fluid can sometimes be the only thing keeping the transmission running so i wanted to see if at this Mileage that would be an issue

I have no experience with your 2007 model (a ZF 6HP transmission), but at 111,000 miles, your tranny is not really high mileage. Personally I wouldn't hesitate to change the fluid and filter. I changed my fluid at 106,000 miles (a 2004 L322 with the earlier ZF 5HP24 tranny), and then towed a 5,000 lb camping trailer for 6,000 miles without problems, including briefly hitting "Overheat" on several steep mountain grades. Admittedly I don't know what the long-term prognosis is, but so far, so good.

In the transmission used prior to your model (5HP24 from 2002-2005), an active FLUSH may replace most of fluid. But a passive DRAIN and refill replaces 60% of the fluid since the torque converter and cooling circuit don't fully drain, common for many auto trannies. A subsequent second drain, if preferred, should therefore result in 84% new fluid. I assume this scenario MAY be similar for your 6HP.

If your shop is not a Rover specialist, I'd suggest finding out the tranny fluid spec and providing that to them, including specific fluids that meet it. I don't know what your ride uses, but for the earlier 2002-2005 model, the spec is LT71141, and Valvoline MaxLife Multi-Vehicle and BG Premium Synthetic meet the spec in addition to the several Euro fluids often mentioned in other threads.

Make sure you get the connector sleeve as they will leak at some point in time and that's generally when the fluid gets replaced anyway. I have 175k and I've changed mine twice, once with the connector sleeve and a second when I replaced the valve body due to a harsh 2-1 downshift.

Thanks for all the feedback! I got it back from the shop a couple of day ago (costed $650 for the whole thing wasn’t expecting that) they check for leaks and found none they replace the pan, filter, screws, and used the correct fluid too! The place I go to is called master mechanics in Kalamazoo Michigan and they have worked on lots of rovers and I trust they have done a good job! Normally with something like this I’d do it myself but the transmission is just one thing I personally don’t want to mess with as we have an 06 RR as well and the transmission went out on it at only 85k miles and I believe that was due to the dealership not filling the fluid all the way back up the the correct point after a harness replacement

Glad to hear they got this matter addressed, ethmail11. Hopefully it will add some life to your tranny over the long term.

For others reading this thread as reference, I should mention that a similar service on my earlier 2004 5HP tranny ran $258, but I can't speak to maintenance/fluid differences between the 5HP and 6HP trannies.
