buurin This is a continuation to this thread. After 3 days I finally have the transmission all apart. Here is the postmortem: Output shaft rear bearing totally disintegrated - plastic retainer vanished, the 7 balls inside ground to some unknown shape. The final drive is all chipped to hell, meaning the output shaft is toast too. This pair is 18/67 meaning 3.722. 5th is 40/29 = 0.725. I'll count the rest of the gears and post them up later. 1,2,5 gears sees slight gouging in the middle. 5th driven gear scraped against bearing retainer plate - a $216 and $112 part respectively Metal pieces everywhere. Inside of transmission case sees lot of gouging and chipping. 3rd and 4th gears are relatively intact. Before the incident it didn't shift that smoothly either, but I have not seen a known good vs. known bad synchros so I don't know how far gone they are, or if they are still good. Geartrain for reverse is for the most part intact. Shifter work also seems mostly intact. My guess at a root cause would be the rear output shaft bearing disintegrating, causing it to shake which then send gear chips everywhere and ruining everything in sight. I have some pics up on my thread on TN: http://www.toyotanation.com/forum/showthread.php?t=381671 I'll have some close-up pics of the input and output shafts posted later. With those pics up, can someone tell if this transmission is worth spending the 4-digit cash to rebuild? Gear ratios after I counted the teeth: (driven/drive=ratio) 1. 38/12=3.166 2. 40/21=1.904 3. 38/29=1.310 4. 31/35=0.885 5. 29/40=0.725 R. 39/12=3.250 Final drive: 67/18=3.722 If info I read off the net is correct, this is indeed a 98-02 C59 which should predate the bearing problems.
