I supposed I could check the kick down solenoid though, How does one check to see if its stuck exactly? I've disconnected the switch for it. 300SD Transmission Dead... From the ATSG Manual: ![]() B2 is engaged during 1,2,3 gears if I'm reading that correctly..

Indeed - but if you had a 100% dead B2 piston then wouldn't you be saying "I can only get reverse"? First gear works doesn't it?

First gear and reverse work fine. Quick to engage and responds fine. Maybe the Kickdown solenoid is stuck? How would I go about freeing it? I don't have any spare to install in its place... I've disconnected it at the switch end. I'll double check the bowden and vacuum cable connections at the transmission end however I doubt its the vacuum since I've had the 300SD disconnected a number of times for diagnostic purposes and the transmission has always upshifted fine. Hard and firm, but fine. Also found this thread with some good information: '91 300D trans stuck in 1st gear... I'm thinking maybe I could cobble together a gauge and check out the trans pressure.. Maybe like the above linked thread something is up with the regulating pressure/governor? I believe I read in another thread that its either 8mm or 12mm. Someone else posted that the banjo fitting from the 617's boost line to alda would work.. ![]() Is the "shift valve housing" the valve body? I can't seem to find the charts/tables they are referring to with regards to regulator pressure hm..
