Gearbox Flaring When Cold Zf Xr6T

[jasol]

Hi guys got a bf 2 xr6t zf box. When it's cold and I'm driving at a steady pace, seams a little worse whilst going up slight hills. It flares. It will hover between 2000-2200 rpm. What could be the cause? Doesn't seam to happen once at operation temp

what oil is in it?

I have noticed mine doing it too especially now that it is getting colder

Only does it once then it's all good when it is warm

I had my zf serviced 12 months ago with genuine zf fluid

Same thing was happening with mine since I had the zf serviced with gulf western syntrans. Took it to a different shop to get looked at and it was down 500ml and the flare seems to have gone away. Its only been a few days so giving it a few more cold mornings before I jump to conclusions but for me I think it was incorrect oil level which cause it to flare

Incorrect oil level is the first thing to check.

Let us know how you go as a few guys have had issues when changing to Gulf Western, others however have not.

Hi guys cheers for the reply. As far as I know it's still the original oil. I've only had the car 6 months. Seeing as I can't check the level can I just go to a trans shop and ask them to suss it?

mine does it in 4th when cold. has Gw oil

[Ralph Wiggum]

Mine doesn't has GW oil.

Get your levels checked people's.

As I've posted before mine was doing it with the factory LG6 fluid. Level was down aprox 500ml due to a leaking mechatronics plug seal. Topped it up with 500ml of GW and the flare stopped.

Cheers guys. Noob question but how do they check it? Computer?

I had the same(ish) problem. I have Penrite in mine, flared a bit, still does a little but generally the shifting is better with fresh oil. I know the flaring is an issue, but I'm not smoking the tyres till I get the temp is up any way. Generally it's worse at about 55 in 5th (I manually set it), if I leave it in 4th til its warm its fine
