===1-2 accumulator=== While it may be true that removing the accumulator spring from the 1-2 servo will firm up the 1-2 shift, leaving the 1-2 accumulator spring out is not recommended. One reason is the accumulator protects the failure-prone intermediate sprag and another is the spring keeps the cover loaded against the snap ring. Photo shows accumulator cover, spring and piston (snap ring not shown). This is located on right side of transmission case. Check the bore in the case for scratches or other damage if the spring was found broken.

Pressure ports are circled. *Rear port (yellow) is main line pressure. You will see pressure here in all gears for most valve body configurations. Some race-only valve bodies may not have pressure at this port or the others *Middle port (red) is 2nd gear pressure *Front port (blue) is third gear pressure [[File:T-350_acumilator02.jpg|thumb|300px|left|T-350 pressure ports circled]] <br style="clear:both"/>
