As a recent convert to XR6 Turbos ( formerly ran XR8s until a  highway patrol friend raved on about how good the Turbos were. He said they all call them seagulls - because they sh*t on everything else!! ) I tripped over this topic and couldn't help but comment. You hear rumours that Gulf Western oils are cheap so they must be low quality, which is far from the truth. Because GW is 100% Australian owned, we don't need to build in $millions in licence fees and royalties to be paid to an overseas parent company - because we don't have one, unlike the multi nationals. We also work on fairly skinny margins because we have got significant growth objectives and we don't want to handicap this by getting greedy. We have grown over 1200% in the last 10 years and have recently put big money into a new state of the art blending plant in order to handle our growth. Yes Syn TS ( formerly called Syntrans ) holds approval for use in the ZF 6 speed in the Falcon and Territory, with full warranty backing,  and we are getting a great following from Ford enthusiast for both this product and our Synex 3000 semi synthetic and Synex 6000 full synthetic engine oils. Our prices are not too low - the others are too dear!  If you need more information look at www.gulfwestern.com.au  , phone 1800 248 919 or drop me a line on this forum if you have any technical questions.

 

 

How many RWKW does your XR6T have?

Getting back on topic, I've since serviced my ZF with GW SYN-TS which has improved it. Definitely made a difference, but seeing my trans hadn't been serviced since it left the factory I'm sure any approved fluid would of helped.

 

Now, one thing I have noticed is if im at 60-70% throttle & in 2nd gear, I can feel the transmission 'slip' into 3rd. I still wasn't sure if it was a slip until today after a squirt at WOT from 2nd into 3rd gear it registered a 'Transmission Fault' on the dash, I turned off the engine & started and it was fine. Any ideas what this may be? Torque convertor not locking properly? As I said, any ideas would help & it will only do it under this throttle application & in 2nd gear.

 

Fluid was changed as per the ZF PDF file on here.

I get a funny feeling the car has been babied most of its life, possibly making me believe the transmissionhas 'adapted' to a lazy shift. Now thinking of tuning it to help these symptoms. 

I've checked coolant & fluid obviously, no sign of milkshake anywhere.

9.897657 times out of 10 it's the shonky fill procedures from the operator of the so called transmission servicer
