Will the transmission in a 1991 420 SEL fit my 1990 560 SEL????

[ron59b]

Good evening all,

I purchased a 1990 Mercedes 560 SEL for $700.00. There are four things wrong with the car:

1. Transmission slipping in reverse.
2. Driver window motor is weak and requires assistance when putting the window up.
3. Need a fuel pump relay.
4. Needed a battery.

I was at the bone yard yesterday and found a 1991 Mercedes 430 SEL that was in outstanding shape. I found a receipt inside showing a transmission service within the last year.

The question I have is weather or not the transmission will fit in my 560 SEL? I have someone ready to pull it for me tomorrow. Do you think the switch could be a DIY job?

Any feedback would be greatly appreciated.

Thanks

Ron
