The last time I had a major maintenance was probably around 35k miles, so I'm overdue.

I think at that time, I did a rear differential flush and a transmission flush

For 75k, I want to do the following services:
Rear differential flush
Transmission flush
Belt change
Spark plug change
Transfer case flush

I have the following questions:
1. Does anyone know a good shop in the SoCal area? Preferably around the San Gabriel Valley?
2. Are flushes necessary or should I just go for a drain and fill?
3. Any services I don't need from that list or any services that I should add to that list?

Any help would be much appreciated

 

Besides engine and cabin filters, I'd look at the brake fluid and clutch fluids. Those get flushed and bled, but the diff and gearbox is just a drain and fill. Same as power steering fluid. What about coolant flush/fill? And the EGR valve. Probably a few others, I'm sure some of the regular contributors will chime in.

 

This^^^^
Also if you have a transfer case you've got a very rare car

 

Rear differential and manual transmission are drain/fill, there is no flush. Spark plugs do not yet need to be changed. Changing the belt is a good idea. Change the oil if it's time. Intake air filters and cabin HVAC filter if they're dirty or it's been a long time. Change PCV valves.

 

I googled G37 EGR and it appears that the G37 does not have an EGR valve. Correct me if I'm wrong?

Lol so I also googled that too, and apparently only the AWD has a transfer case

They don't do flushes of rear differential and manual transmission fluid? Ok, cool, I'll just drain and fill those then.

I think my new list is now this:
Drain/Fill Manual Transmission Fluid
Drain/Fill Rear Differential Fluid
Drain/Fill Power Steering Fluid
Flush Brake Fluid
Flush Clutch Fluid
Flush Coolant Fluid
Change Serpentine Belt
Replace Engine Air Filter
Replace Cabin HVAC Filter
Change PCV Valves
Throttle Body Cleaning

Is there anything else I'm missing or don't need on that list? Thanks a lot for the help, guys.

 

im in san gabriel valley too.... any good shop???

 

That looks like a good list to me. Best of luck.

 

BB, why not plugs?

 

The OEM plugs are still good. The recommended change interval is at 105K. Even then it may not really be needed on a completely stock car.

 

OP - I meant PCV valve as BB correctly stated. You're right, we don't have EGR valves.

 

I thought I needed spark plugs, but when I went to the dealership, they told me that my rough starting was most likely due to how dirty my throttle bodies were and not due to the spark plugs.

Thanks for all the help

 

Ah, okay. Yeah, I'm a noob and don't really have much of an idea of what those do besides what google told me lol

 

So my car is currently at 38500 but it's an 08. Would you guys recommend me doing everything like his list like at 50000 miles? I mean it's only 38500 but it's 7 years old already...

 

^ yeah, i'd get them all done. like you said, it's the elapsed time that trumps the mileage in your case. if all the fluids (except engine oil) are original it is past due for some of them. your drive belt may be ok depending on where you live so have a look first. it's a cheap DIY so no big deal, but might not be required yet. and no spark plugs at your mileage.

 

Thanks man. I actually looked at the carfax that I had printed out and it looks like for some of it, I'll be okay. This was on there from 07/06/2013 at 31,869.
"Maintenance inspection completed
Power steering fluid flushed/changed
Oil and filter changed
Rear differential fluid flushed/changed
Transmission checked"
Lol but from 07/06/2013 to 04/13/2015 which is close to 2 years... they drove the car about 2600 miles... I already put over 4500 and its been 2 and a half months!
