shiryo Posted January 21, 2013 Author Report Share Posted January 21, 2013 Ok after many questions with friends and some mechanics at work they said it could be due to the torque converter coming too far forward on the shaft causing it to misalign. This seems to make sense as everything else seems good. I'll try gain access to it over the next couple of days and see if it free spins like it's meant to and get it to align again. Will post if successful. Thanks guys Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted January 21, 2013 Report Share Posted January 21, 2013 I thought the torque converter bolted to the flex plate, the plate that replaces the flywheel in a manual. So the torque converter is fixed in place. Mind you, I've never owned an auto, only pulled them out. Quote Link to comment Share on other sites More sharing options...
oldie Posted January 21, 2013 Report Share Posted January 21, 2013 Thats my understanding also,auto has a flex plate mounted to the crank,not a flywheel and the converter is mounted to the flex plate and then when you fit the auto you slide the splines into the converter,this was the case on my 4k auto anyway!

tojo2 Posted January 21, 2013 Report Share Posted January 21, 2013 How far forward converter goes on shaft would depend on thickness of plate between bellhousing and block. don't know if it matters tho. Could be different thickness of 3k / 4k plate Quote Link to comment Share on other sites More sharing options...
tojo2 Posted January 21, 2013 Report Share Posted January 21, 2013 don't know if possible or what it looks like, but if flexplate is dished and flipped it could also cause the converter to be in the wrong place Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted January 21, 2013 Report Share Posted January 21, 2013 Nah- flexplate is flat. maybe possible to put it on the crank backwards. The torque converter bolts on via the the holes at the outside edge. Quote Link to comment Share on other sites More sharing options...
shiryo Posted January 21, 2013 Author Report Share Posted January 21, 2013 Is there a difference between the 3k and 4k ring gears? I highly doubt there would have been. However that said, working in spare parts for Toyota I've seen more than my fair share of stupid supersessions and minor design changes for no particular reason. I don't believe I've bolted the ring gear on incorrectly. That middle protrusion in the ring gear should recess into the hole at the back of the crank area, where the otherwise spigot bush/bearing would sit if a manual if I'm not mistaken? If I am, well....that's probably my problem hahaha. Quote Link to comment Share on other sites More sharing options...

I reckon. It was quite random, but the flywheel and the flex panel are the same way up in each photo. If you enlarge it you can see where the starter gears hit the flex plate in the top photo, so that side goes onto the crank. Quote Link to comment Share on other sites More sharing options...
shiryo Posted January 22, 2013 Author Report Share Posted January 22, 2013 So it appears I have installed it correctly. I'm hoping the issue is a simple misalignment and nothing more. Thanks for all the input guys, I'll keep you posted. Quote Link to comment Share on other sites More sharing options...
tojo2 Posted January 22, 2013 Report Share Posted January 22, 2013 Is there a difference between the 3k and 4k ring gears? Didnt mean ring gears.. I meant the thin sandwich plate that goes between the gearbox and engineblock. It comes in at least two different thicknesses. Should be ok if you used the one from your original 3k auto setupp Quote Link to comment Share on other sites More sharing options...
shiryo Posted January 25, 2013 Author Report Share Posted January 25, 2013 I had given up by Wednesday night and took it to a local workshop my workplace has a good relationship with. Torque converter was slightly misaligned, but not badly enough I couldn't engage any gears at all. No vac leaks. Needed another 2.5L of trans fluid - which is strange as I dumped 4L into it as per owners manual said. Even for a dry fill it should have only been about 4.5? Perhaps the torque converter itself had dumped all its fluid. Still hunts for idle a bit, not nearly as bad though and appears to be quite drivable and it feels amazing to be behind the wheel again. Thanks to everyone who provided knowledge and assistance as usual. Members on here are so helpful in comparison to nissansilvia haha. Thanks guys!

B.L.Z.BUB Posted January 25, 2013 Report Share Posted January 25, 2013 Ah sometimes you just have to bite the bullet and take it to a mechanic. Strange about the fluid, sure there isnt a leak? Quote Link to comment Share on other sites More sharing options...
shiryo Posted January 26, 2013 Author Report Share Posted January 26, 2013 Would have to be a substantial leak to drop 3L of fluid in my garage, would also need to be magical as I never saw it hahaha. Torque converter was just dry I reckon. Hasn't being leaking yet. Things are looking up. Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted January 26, 2013 Report Share Posted January 26, 2013 Now you know why they have a dipstick! Nice that it was a cheap and easy solution. Quote Link to comment Share on other sites More sharing options...
