interested in converting 300cdt from automatic to manual
 

I'm wishing my 1982 300cd was a manual...faster pickup, more control. Can this be done? Pluses, minuses anyone?

Thanks.

I'm wishing you'd go take a look at that trunk badge...... :D

plusses are that you will lose about 100 pounds in weight, minuses are that you have to spend a good 8-10 hours removing your old tranny, and installing a new one with shifter, master/slave cylinders, pedal cluster, and new speedo cable and other stuff related to this swap, and spend some good money on it, too. more plusses are you never have to worry about tranny oil again, or about vacuum modulators and all that crap

guys, it's becoming apparent how batman got his 8k+ posts. it's with brilliant observations like the ones above.

hey, jimmy, what's the badge on the batmobile say?

Do a search, there is plenty of information regarding this swap.

Well put

if it bothers you so much add Jimmy to your ignore list. my guess is you will miss the information he provides.

to the OP, yes it is a lot of work to swap, but I really enjoy my coupe with the 4 speed, if you are really motivated, swap in a 2.47 rear, that has been as good or better change as the 4spd

Last time I checked, manual transmissions still had fluid that needed replacing at regular intervals.

yeah, you're right, they do have fluid, but you only have to worry about replacing it when you do a clutch kit. let's just say, if your manual trans feels good shifting into gear, you don't have to worry about checking fluid levels or anything fluid-related, so that's a plus

nah, i'm just instigatin'

Jimmy,

I'm not looking to race, just to get on the highway with a little more power and better fuel economy. I've read enough to know that they made the 300cdt in Germany with manual transmissions.

What's your point anyway Batman?

What is wrong with a little tonge and cheek humor? don`t get your knockers in a knot :P.

The Trunk Badge of Truth

He's battling the myth of the extra T. Your trunk doesn't say 300CDT on it, just 300CD.

Back on topic. So, lutzTD, does the 300cd have a slightly shorter wheelbase, for reference when modding the various parts?

When I did mine last April, I pulled the engine and trans as one unit. or as others have done, drop the auto and install the manual trans.

I prefere the first way.

Get all your parts together, a donor car works, but I got all mine from the JY off a 84 240D. put my list together as to what I needed, and it all went together w/o too many problems.

Pilot bearing
flywheel
flywheel bolts
clutch disc
pressure plate
throwout bearing
slave cylinder
master cylinder
peddle assembly
rubber hose to supply MC fluid from the brake reserve for the hydraulic system
two metal clutch lines.
one from MC and through floor under accelerator peddle.
second from slave clylinder, over trans., and connects to first line.
shifter assembly and shift rods.
front section of 240D driveline
240D metal X mount off a 240D with automatic trans.

think that is it.

pretty much plug and play except for having the driveline cut and balanced and having the flywheel matched balanced to the automatic FW.

will have to shorten the shift rods, bend and thread them to fit.

You will also get rid of a lot of vacuum lines.
the accelerator peddle is a lot smoother now also.

You have the 3:07 Diff and I have the 2:88. you will have a little better acceleration. I have no complaints with ours. and I have picked up 2 1/2 to 3 mpg. 9-14-09 coming back from Cottage Grove, Oregon the Lathrope,Ca. I got 31.94mpg.
