all the OD accumulator does it keep the shift from engaging hard. basically when the gear is engaged the od circuit is filled with pressurized fluid but before it gives full pressure to the gear it must overcome the pressure of the spring on the accumulator piston. it makes it shift softer (SLIP) if you were to block a portion of the pistons travel with a rod or put in a heavier spring it would just shift firmer due to faster engagement of the gear.
This past weekend I tore into the trans to check out the valve body to see if it might be the culprit. I took apart every valve and small parts to make sure everything was in there correctly. Everything checked out...except for the OD accumulator clutch spring. What was in there looks like one of the springs included with the transgo shift kit. Luckily I just picked up a trans that I could rob the parts off of (Thank you Flores and Mike!).
Pictured on the left is the spring that I took out. The two on the right are what were supposed to be there.
From the transgo shift kit instructions...
Gotta love finding all these mistakes in something that I had paid good money for. :gonnablow This thing has been fighting me for over a year now. It makes me wonder what else could be wrong internally.
It does seem to shift better, and not require as much throttle in over drive to maintain speed. I'm hoping it'll now pass emissions so I can finally start driving this thing again! :confused1
