Slow shifting into reverse

[dboyw]

I have a 99.5 that I was able to replace the stock trans with a BTS trans. At the same time I finally put in a DP tuner. All has worked good, and still does. But it seems to be sluggish going into reverse from either drive or park. When stopping to go into reverse, I come to complete stop, shift into reverse and wait about 3-5 seconds until it goes into gear. Fluid is full, not burnt in color or smell. 6.0 cooler keeps it nice and cool, about 60* over outside temp. No noises or anything that would give me an idea. No leaks.

Any ideas?

Thanks

I have the same issue, would like to see what people come up with.

I'd reload the stock tune and see if it gets any better. If not I think it's time to talk to the trans builder.
