Interested in the Nulon trans fluid being used and any feedback.
Wondering at what point my “new” 2015 gc with 60k on it will require a transmission oil and pan change?

So far the Nulon has been faultless, very smooth changes, and when towing the temps hardly move so I'm sold................ At 60K km I would be getting it changed, I bought mine at 40K km and did it at 43K km and its been done about every 40K since................... except the last one it was a 20K km change........

I found a ZF note, basically says the drain plug is only to be used to drain the pan so I think its a one timer and maybe checking tension is a No, No........ I may have mozzed the last one when I put it on...


Captiva has a plastic inlet manifold, so has ours, it also uses the same oil filter, I wonder if its a VM engine.....

Did you get the transmission fully flushed or just drop the pan and refill the 4 odd litres you got out with Nulon?

They did the lot, you don't flush these boxes you have to follow a certain sequence but I have only ever dropped 4lt and refilled even when I dumped the original oil, didn't seem to upset it, at least a new filter and half oil is better than than none ..... By the time my box had 100K on the clock it had 3 filters and 12 lts of new oil rotated......... Even though you can get the Nulon in squeeze packs I think I would get it by the keg and use a pump............ and with the drain plug saga I don't think I would be doing a drain and fill routine on it, I think I did one after my first change to have newer oil in the system but never did it again....it was pan#4 that dropped the oil.

Re the Nulon trans fluid, is it just there standard fully synth fluid ?
Re trans pans, do you buy generic ones or Mopar pans?
Last one i bought from Jeep .

This one https://www.nulon.com.au/products/au...-low-viscosity

Pans I would buy online from this mob, https://www.ebay.com.au/itm/193621236846 they are the proper deep pans for the Grands and Landys, only the last one the plug broke but then it seems others have done the same and I would think its a design problem possibly... The one the shop put in was $300 but I forget to ask from where... the important thing is there are deep pans for the FWDs and shallow ones for the cars, they will all fit ..... so if its marked BMW it probably the shallow pan.... I have ordered a Wesfil one identified as for the WK2 but it was the shallow so sent it back .....
Most important you do it the right way ... ideally with a hoist as you must run the engine, work thru the gears half way thru the refill and keep it idling while you pump in the last litre, when it dribbles out then replace the bung before you shut down then you will have the right level.... at least I think thats how I do it, I have notes in my shed..

I doubt there wouldn't be a late model car on the road that doesn't have a plastic inlet, even my VZ SS 6lt Thunder ute had one. The 4b11 in the
wife's Mitsubishi ASX.
They are actually Plastic Composite, some have fibreglass infusion, next to zero heatsoak, better heat tolerances
