Ok so I recently put a five speed d/r into my Brat. Had a few problems with not going into reverse before, put the shims in the bolts and fixed that problem, but now its doing the same thing as before. Except this time it only when my transmission is cold.
I live in Colorado and we've been having some cold nights and It like reverse doesn't exist, but the second I drive for a few minutes and warm it up its perfectly fine. Only does it when its colder than about ten degrees.
Anyone have any ideas how I could fix this? Possibly an idea for a "cozy" or some sort of way to keep it warm at night.
