The reason your car bucked when you downshifted into 1st is that you probably did not rev-match correctly. I've chirped the tires when downshifting into 3rd at the track because I did not rev-match correctly; messed up the heel toe and revs dropped too much before releasing the clutch.I always pass thru neutral FIRST (I think), and I am not sure if I actually did that...it may of been from 4th the 2nd ....then again, it may of been 3rd to 1st....
But ....did they say why? And maybe whatever the reason is not to, if I DID do that, that's why it gets the car to buck a little?
Anyone else has some minor jerking/bucking?
I may of done it twice....ever.... but getting un understanding of this really helps. I will know not to do it ever again, if I had!!!!
You run the risk of over-revving the engine if you shift into 1st at too high a speed.
Another reason is that you risk mechanically damaging the transmission. I am not sure about the GT350, but on my 2012 GT with the MT-82, the manual had specific instructions that shifting into 1st above a certain speed (something like 10 mph) will damage the transmission.
