i just purchased a slightly used 4.1 and went to use it the first time and the trans won't shift out of first. i had a hobby shop look at it and he said that the internals all look good just hasn't been run in while and thinks it just needs some lubricating. does this sound about right? we did try adjusting back to the stock setting and still didn't shift before the tear down of the tranny. we tried all the adjustments shown on hpi's website still nothing. I'm gonna call him on monday to see what he found out for me. could it be engine tuning preventing the trans from shifting? I'm new to all this rc stuff so I'm not 100 percent sure on the tuning. when i was running it in first gear there was a nice blue smoke trail coming out of the exhaust so i know thats good i just can't adjust anything else without it shifting. any help is greatly appreciated
