Ninja085 Member 2 Member For: 10y 2m 18d Posted 25/11/14 11:23 PM Share Posted 25/11/14 11:23 PM My BF XR6t recently had the coolant mix with the gearbox oil. Had gearbox rebuild. Got the car running but when shifting down from 5 to 4 there is a very hard gear change, can hear it and feel it through the driveline. Took it back to gearbox shop and they sent the mechatronic from the gearbox to zf to be checked and come back ok. Valve body was ok. They said that I just need to drive it for up to 1000km for the gearbox to relearn and self adapt, does this sound like bullsh*t or is that how it works? It was shifting fine before it went away. 1 Link to comment Share on other sites More sharing options...

discostig Manual mode ________________________ All day, erryday Donating Members 13,798 Member For: 17y 2m 19d Gender: Male Location: Probably above atmospheric pressure Posted 26/11/14 04:59 AM Share Posted 26/11/14 04:59 AM I had a very badly worn out ZF rebuilt to stage 2 spec clutch packs, when I got it back the thing was smashing horribly into gears all the way, as it still thought things were spaced miles apart.Took aaaaaaaaaaages to relearn. Like 10,000km. Might be because I drive in manual mode most of the time. I'd suggest leaving it in D until it sorts itself out.Be thankful it's just one gear!

***VX*R8*** Member 202 Member For: 11y 3m 29d Gender: Male Posted 26/11/14 10:18 AM Share Posted 26/11/14 10:18 AM My g6et is shifting too firm at partial throttle lately too.I recently did a trans service and after the shifts felt perfect but over the last couple of weeks have gotten too firm at partial throttle, it feels like it shunts/jolts a bit just driving normally. I noticed in manual mode it shifts nice and smoothly though.I've been disconnecting the battery to try and get it to relearn and shift nicer which has worked for me in the past but after reading this thread I think that's just making it worse this time.
