Well, we have replaced all the worn and suspect parts in the transmission including all steel and friction clutch plates, the intermediate band, the sprag clutch rollers and springs, the govenor and front pump rings, the front pump gear set, all thrust washers and the modulator valve. We have also replaced all rubber seals for the servo pistons, as well as the forward clutch and reverse/high clutch pistons, as well as the shuttle valves inside the valve body. The torque converter required replacement on account of water damage from storage and the input shaft was missing, so a suitable replacement was sourced. There was considerable evidence that the transmission had been meddled with in the past, with some satisfactory repairs, as well as some less than desirable ones. The absence of a valve body gasket, a rock hard forward clutch inner o ring which broke in a few places on removal and the piece de resistance; a broken spring retainer on the line coasting boost valve, which had metal fragments broken off from where the retainer had been forced in (presumably with a hammer). The spring was half poking out as well. I couldn't remember what the end play was during the video, but I'd written it down at the time of checking and it was 1.68mm!
Anyway, this is a long video at an hour, so I hope you enjoy!
