Transmission vacuum line question

[GloNDark]

I've been figthing some strange transmission issues with my C4. Weird intermitant no reverse, strange 3rd gear shifting/non shifting.

I changed out my reverse servo piston, and put another new vacuum modulator in there. But I was realizing that my vacuum line from the manifold is ALL RUBBER, could this be part of my problem? I know stock they were steel with about 2" or less of rubber.

Obviously seeing as mine was originally a manual, I don't have the stock steel one so, can a steel brakeline be used instead?

opinions?

Thanks!
Chris

Yes, It needs to be steel. Over time, that length of rubber will not support itself, especially with all the heat. I used some 1/4" steel line from part of my vapor emissions system on mine.
