1990 260E Sportline
Please help! Urgent guidance needed :( M103 to M102 Manual Transmission Swap

Hello everyone,

Really need some help here. Have a 1990 M103 260E Sportline stock 4 speed manual that I'm looking at swapping with a 5 speed manual box from a 190e M102 5 speed.

The torque converter in the auto box has busted & i was already having problems with the transmission so I figured i'd try manual swap for the benefit of everything.

I'm just in dire help of WHAT EXACTLY DO I NEED?

I understand the bellhousing is the same, but what else? I know i need pedals shifter etc.

What about driveshaft? clutch & flywheel is getting me confused? and anything else??

Please assist me if you can,

Any help is much appreciated, thanks for taking the time to read my post.

Pretty much everything has been said on this issue. However I don't think I'm leaving a HVB charger connected will do the job.
Once HVB has reach set maximum charge (ex: 50%) the HVB charger stop working. The 12 V battery is prone to faster discharge rate than HVB which will not be recharge for a long time before the HVB kick in again at least for the models that dies net benefit from De that check and maintain the 12V battery.

For those reasons I suggest a 12 V trickle charger is still a good thing to do.
