·I wanted to share my “shifting
I wanted to share my “shifting” experience and see if the more experienced group out there thought it was normal.
This is a 72 US C4 with 42K on the odometer when I bought it – 15777 – I have very little history on the car prior to 1992. Body was in great shape (some cracking paint), but does have a cigarette burn in the carpet to the right of the passenger seat - apparently done on purpose.
When I got the car, shifting into second was an exercise in “grind avoidance”. First thing I did was pull the transmission – put in 5 new syncro rings – Reverse was virtually new so I just flipped it over. I put in a new 1st/2nd slider and 3rd/4th slider ($400.00 each) and filled it up with Redline shockproof fluid.
So – now that everything is new – it ought to be perfect, right?
Shifting into second and third at my casual (BMW rate) I still get a distinct gear “hit” where the syncro rings are not quite resolving the rpm difference. Shifting slowly – works fine. Also, shifting hard/fast works great as well – so I need to be really patience or I need to slam the gears- the casual shift situation does get better as the box heats up – as I have heard it should.
In my pursuit of perfection – I switched over to Swepco oil - the stuff all the Porsche people recommend for Porsche style syncros – The above situation slightly degraded – what I believe is that the Redline shock proof tends to be thinner at room temp. and it takes a while (It is natural mineral oil) for the Swepco to heat up and thin out. Also the Redline has a more “cushiony” feal – I will go back to it next time.
