727 doesn't shift into second gear like it should

no problem. If there is no spring at all in the accumulator you need to make a blocker rod like scamptramp said because with nothing to hold the accumulator piston stationary it'll slam back and forth and eventually break.



I was reading over the instructions tonight for a refresher before I go back into it. The instructions say to take out the accumulator spring and thats it. No mention to block it with a rod or anything. Guess that is why I just took the spring out 20 years ago. I will make up a rod to put back in it. Scamptramp mentioned the rod length, but what about the diameter, maybe something around 3/8"?
