D&D Viper T56, 6 gear grinding when letting out clutch? Wont stay in 6th!!
I bought this transmission a few months ago it had about 10k on it. It's a 30 spline running a Dennys driveshaft. I have never noticed any problems with this transmission any of the times i took it on the road but today i was coming down my driveway (its long) about 30 mph and was going through the gears and went to put it in 6th at a low speed and let the clutch out and it just grinds and pops out of gear. Why is it doing this?! I dont have a reverse lock out hooked up but it cant be shifted into reverse without it. I have never mis shifted a gear or anything on it. I have probably only put maybe 10 miles on it since ive had it.
What could be causing this? This was not a cheap transmission and i neve thought i would have to worry about it! I do have the connector to hook up the reverse lock out, should i try installing that? I dont see how that would make a difference though. Also the rear seal is wet, i wouldnt say leaking but supposing all of the fluid did leak out somewhere mysteriously would that cause it? I just checked the fluid a day ago and it was completely full so i doubt thats it. Im getting ready to go under it and see.

I remember the guy i bought it from mentioning it had adjustbale stops for the gears, i hope thats it. I think he said it was a hurst shifter, are there any write ups on it? I am running Mobile 1 ATF in it, trans has steel shift forks and carbon blocker rings.

Hey Mike! I think its gotta to be the shifter stops because thats all that could make sense to me. It's driven perfectly fine when i had it on the road, no hard shifting, i think they just may have vibrated loose in the hours of testing and tuning and such ive been doing. How would i go about adjusting them? I have read to put thread locker on them.

Haha i almsot took off the 4 bolts to get to the stops but then i was like hmm i wonder if its under the shift boot. They were touching with the shifter in gear so I'm pretty sure that was the problem. They werent loose though. I did find water sitting in the top of the shifter which was a little brown in color obviously from rust but i cleaned it all out and nothing has surface rust on it. I am sure this was from the rainstorm that my car got left out in with no glass in it. After i cleaned it all out i sprayed some pb blaster on top of the shifter to help re-lubricate anything the water may have damaged. It shifts really nice though, i think that it was just the shifter stops acting up.

Thanks for the interest. Sorry, no vids. It's a road course driving specific car & it is bad *** in that setting. Built from the ground up w/ proper sub-frame & suspension, Miata's are great street/road course cars. They're not much on a drag strip due to their short wheel base & limited rear tire size. Overall, a lot of fun.
It's either raining or snowing here, far too often. It's the ornamental plant nursery capital of the US because of the wet weather conditions during the Summer & Fall. There is no Spring. Weather goes from a snowing Arctic cold, to a wet humid Summer, then into a short wet Fall prior to becoming Arctic once again. For this reason, is an Arctic rain forest.
