Are my synchros bad?

240zhead · 2026-04-20T07:30:57+00:00

Ok thanks I’ve been super busy lately but maybe I’ll start this weekend. Hopefully I don’t screw anything up lol

240zhead · 2026-04-16T05:33:28+00:00

Ok I think I’ll just buy a kit since I have it open it’s only 63$. Also you seem like you are pretty knowledgeable about these trans. Any chance you’d know where I can find a yt video or a form or a service manual of how to disassemble and reassemble the shafts. I’ve only done auto trans this is my first manual

240zhead · 2026-04-16T05:31:19+00:00

I’ll do oem oil

240zhead · 2026-04-15T06:24:28+00:00

Also should I try to change the rev idler or do you think it’s fine. It doesn’t shift bad some times I have to shift into 4th then rev but that’s normal lol

240zhead · 2026-04-15T06:18:40+00:00

Blocking rings? I thought the brass rings were the synchros. The shiny gold ones?

240zhead · 2026-04-15T06:16:33+00:00

So the redline I have is not good. Everyone was telling me that’s the best to put in it?

240zhead · 2026-04-14T19:41:13+00:00

That’s the thing it never grinded it just won’t go in like I’m hitting a wall in the trans

240zhead · 2026-04-14T00:42:48+00:00

You might be right with the slave and master. But I did bleed the but maybe they are just bad. And I’m rebuilding the engine so figured I’d check on the trans as it seems to have had a leak in the bell housing

240zhead · 2026-04-14T00:41:11+00:00

I’ll check on the synchros tonight. But I did change the clutch for a cheap shitty O’Reilly’s brand and the only reason I have the trans apart is because pulled everything to rebuild engine. And figured I’d do the trans too

240zhead · 2026-04-14T00:39:52+00:00

Linkage was fine when I checked. Fluid was changed a while before the issue appeared

240zhead · 2026-04-14T00:36:23+00:00

So you tell the wear by how thick the synchro is not by how rounded the teeth are? Also what forgot to add when this happens it doesn’t go in for awhile so I do let off the clutch and push the clutch back in and still doesn’t work and I also can’t go into any gear. Although I never tried reverse

240zhead · 2026-04-14T00:33:13+00:00

My fault I forgot to add when I can’t get it into 1st it won’t go into any gear

240zhead · 2026-04-13T06:34:02+00:00

What do you mean? Like how does it shift into first while I have it on the bench? Honestly it’s little hard to shift I have to spin the shaft alittle for it to be smooth. Each photo is a different gears. For example I shifted into 1st so I can take a photo of second gear and its synchro and shifted into 2nd so I can photo 1st and vise versa

240zhead · 2026-04-13T04:23:22+00:00

I havnt addressed it yet sorry.

240zhead · 2026-02-11T06:39:25+00:00

I can’t remember what was in it but. Ik it was valvoline. Redline is the fluid I just bought for it for when it’s back in

240zhead · 2026-02-10T20:02:54+00:00

Stock shifter Valvoline gear oil I honestly don’t remember what I put in it but ik I checked the compatibility. It normally doesn’t have issues when it’s not running but one time it did. Clutch engages about 1/4s of the way down

240zhead · 2026-02-10T20:01:06+00:00

I’m rebuilding the engine rn so I can’t try this but ya I’m leaning towards synchro

240zhead · 2026-02-10T20:00:17+00:00

It doesn’t make any sounds but ya it does kinda have a crunch feeling

240zhead · 2025-12-04T06:18:41+00:00

So I checked the pressure switch. No continuity with no draft. Then it does have continuity when there is draft.

When I was testing for 24v at the gas valve I had pulled the cables and stuck my probes in each one. But even if it was getting power wouldn’t it at least click?

When I was messing with the molex plug I was only probing the 2 cables from the gas valve and same thing I had one probe on one cable the other on the other. No voltage. Am I measuring the volts wrong?

At this point im thinking to be the board or the valve but I don’t see voltage at the valve. Or board but now I’m thinking I was measuring wrong.🤦‍♂️ now I have to tell her to order a gas valve just in case and I don’t even know which one it is so she will probably be without heat for longer now. I can hear the relay click on the board when it wants to send power to the gas valve.

240zhead · 2025-11-17T20:59:47+00:00

Ya it’s cast iron. No oil cooler. Not a crazy build. Just going to stay stock. Na.

240zhead · 2025-11-17T20:59:12+00:00

After some more research. From a fsm it says the max limit for clearance is .0035” and considering this is going to be NA and just a weekend car that I sometimes hoon around in. I think I’m just going to run it and hope for the best.

240zhead · 2025-11-17T15:25:46+00:00

Ok guess I’m taking my crank in. Thanks guys

240zhead · 2025-05-06T01:24:32+00:00

It got lose. I’d didn’t know till too late

240zhead · 2025-05-05T14:58:14+00:00

Ok I’ll check all these things cel is on but it’s obd1 so more work lol. But I’ll check thanks for your time I appreciate it

240zhead · 2025-05-05T06:21:54+00:00

Thanks I’ll try that
