Thud when engaging 1st anyone else? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

earthsscum · 05-31-2012, 07:04 AM

2nd day with my brz.. not my first m/t car I've owned many

When at a stop and i go from neutral to 1st i sometimes feel a thud when i engage the gear.. it shifts into the gear smoothly but once in i feel a jerk in the car.. the first time it happened i thought a car behind me tapped my rear bumper.. its very strange and doesn't do it every time.. its subtle but definitely noticeable.. and its before i slip the clutch its only immediately after engaging the gear

Anyone else notice this?

Mine does it as well.

Might this have something to do with the hill-holder?

sounds like the rear diff, pretty normal on rwd MT cars

I hate it when people tailgate at a stop. I hate tailgating period.

I hope this is the case any data on this for the frs/brz specifically

My S2K would do it every once in awhile also.

The BRZ is very hit and miss with it.. today it hasn't done it at all, yesterday probably 50% of the time.

My BRZ does it as well. It's as if the clutch doesn't fully disengage.

I'm having trouble getting my shift points down. I think it's a mix of a lighter rotating assembly and overly light clutch.

Oh hey I just posted about this in a different thread.

I think its just the syncros stopping output shaft.

I haven't tried this yet, but try waiting for a while after you stop before shifting into first gear, for the output shaft to stop moving.

That works, I suppose I could have mentioned that before since I tested it at lunch and came to that conclusion

Slightly off topic here. But does the manual BRZ/FRS actually have a hill holder feature?

Just wondering because this will be my first manual car and I would love to have this feature. One of the things which scares me is starting on hills with a manual. So the whole automatic break thing is pretty sweet.

I'm just not 100% sure the BRZ/FRS has this or not.

Mine rolls nicely on hills

So I'd guess no.

The e brake is basically where your hand rests. It works well as one if needed.

That's what I expected you to say.

Thanks for this. I didn't think this car had such feature.
