Hi Ants,

I left my car at 'Harveys' - in Essex for the whole day (8-6pm), I don't know how long the job actually took, but they charged around £200 + the dreaded VAT. I've used them before and they seem like genuine blokes - know what they are talking about, and they race 924's and 931's.

Jason,

"The 76-78 cars were delivered with a 4-speed transmission of Audi origin. This transmission is fairly robust and common, but not the fastest for the car.

Then, in '79, a 5-speed trans based on 915 internals (the trans used in late-70's 911's) was introduced. This is referred to the snailshell, because of the pattern of the diff housing (see picture below). However, it is even more easily identified by the shift pattern - 1st is directly below Reverse, with the main H-pattern formed by 2nd-5th. Due perhaps both to the unusual shift pattern and the internal design, these transmissions tend to be in fairly bad shape in most 924's by now, with synchros on 1st and 2nd gear usually gone (identifiable on a test-drive by crunching when shifting into those gears with the car moving). Unfortunately, they were only in the '79
924's, so not all rebuild parts are readily available."

Teo,

The same 'snailshell' transmission was fitted in to the euro model 931 right up to the end of 1982, the ratio's may have been differant though, but the internal working are the same. Its a good strong transmission, but with a huge appetite for synchro's

Kevin,

tell that to 924RACR, the Webmeister!



ps: and I am serius, the '79 VIN decoding in the 924 Garage Registry should be corrected also.

Let's make PCA international!!

The 924 I wish to purchase has a snail shell 5 speed. The synchro for second gear is shot. If you have a spare tranny, and you swap it, can I have your 2nd gear synchro? please?
