Hi i have a 300e auto 1992 can anyone tell me how many gears it has? It seems to be a 3speed is that right?

Many thanks

As above but you need to kick down to engage first

 

[stumpy]

Your gearbox gate will say PRND32 making it 4 speed

 

[jonviola]

Ah that would explain it! Did they ever do a 5 speed box? Would that help the economy?

Yes yours is the 722.4 and the 24 valve version had the 722.5 offered as an option,, it was a solinoid operated 5th

5 speeders are quite rare and seemingly desirable, but can be troublesome. 3k rpm on a motorway cruise doesn't do your mpg many favours, and is the only time I'd like an extra gear.

To be truthful Stumpy the main faults are vacuum pipes and not the 5 speed box its self

My vacuum system has just been repaired funnily enough.

Please dont take it the wrong way but can I say that you are a bigger sucker nowand much smoother changes

Four

Actually I should have said "Probably four". The 5-speed was an option from 1991/1992 but I've never seen it on a 300. I've seen it on 300-24 valves, though

Thats correct and was first offered on the 24 valve engine, it stayed an option. I dont think that many other cars used it

 

[jonviola]

So is it a desirable/possible change for a 12v 300e? I definitely know what your talking about on the motorway hence the post....

 

[television]

Yes quite a few have done the mod it knocks a chunk off the RPM''I have a chart somewhere with the difference,, see if I can find it

 

[jonviola]

Brilliant, thanks.

Put you Email address up for a few mins,, and you can go to edit and remove it when I say

 

[television]

OK take away your address,, I have only got the shift points for that box but it will give you a fair idea

 

[television]

The thing to do is to buy a box from a breaker with the ECU and loom

Price wise I have no idea

I have a 5 speed on mine which is a 00 car on a 91 plate.

From memory it cruises at an indicated (ahem) 90 - about 80ish at 3500 rpm

It's a "non-trivial" task (as the Americans say) to install a 5-speed. It needs the box, speedo, ECU, wiring, lever/housing and probably a few things I know nothing about
