Freds 73 Scamp restore on a budget

Did you find any drawbacks to the gear vender? I think we discussed this but I forget. Something about revers or something. IDK, maybe someone else.
We talked about it and yes reverse. If you do away with the computer and run it on Manuel than you best not have it in over drive when you put it in reverse you will toast the over drive. But easy to fix on an automatic. I like it,been running it for 2 years and no problems so far and will handle more HP than I'll ever put in front of it.
