[W126 Coupe] Transmission advise for an 83' 380SEC

[Barry Corno]

Your best bet is to rebuild.
   158K is all you can expect from an original one.
I have had two rebuilds for $1500.00. Both have gone 200K
1st one at 138K second at 400K. Now at 517K I can expect
Another 80K + miles. Serviced every 30K. On the rebuilds
The new parts replaced are better than what comes with the
Car.

My transmission stopped changing to 4th gear (158,000 Miles). It started
off with refusing to change up 
when the engine is cold to now not shifting to 4th. Other gears seems to
function ok.
What I have done so far:

 1. Changed the fluid+filter including the Torque converter. 
 2. Adjusted the Modulator (hard to soft back to hard shift). 
 3. Replaced the break booster vacuum line due to a leak.
 4. Checked the fluid level.
 
The old fluid looked clean after 30,000miles.
Is there something I can do short of buying a used or a rebuild
transmission?
If I were to consider a transmission, can I use one from a late MB *like
the 500E*?

Thanking in advance for your help,
