Turbo350 w/shift kit slamming 2nd gear

How do we get the accumulator cover back on? Can't figure out how to get the snap ring back in the groove while pushing on the cover hard enough to see the snap ring recess. There has to be a trick to it. TH350 is still installed on the truck.

Yep, Matt said the trick. Most people put that O ring over the cap and try to push it in place. NOPE. Put the O ring in the groove of the case FIRST, THEN push the cap in and set the snap ring.
