How easy it to install a B&M Shift Kit Improver? I have a friend that said he would do it for $30 dollars but I'd like to do it if it's not that hard. I really want to do all the work myself on it!

 

The b&m shift improver kit is fairly simply to put im i dit it on a 700r4 for a friend in about an hour.
you have to drill a pasage in your valve body if you, replase the pressure regulator spring i think 2 or 3 springs in the valve body. and put the spacers in the acumulator.
I say give it a shot just take your time and if you have any questions ask ythe board. In my opinion the trans go shift kit is worth the extra money but the B&M will give you what your looking for better shifts. the trans go gives you springs for all the valves in the valve body.
GOOD luck

 

just did it on my th-350. started after dinner got it all rippped apart and put it all together the next morning. took no more than 1-2 total hours to do.
