Flywheel convex ?

So I'm doing a clutch job. Really I'm just replacing everything exterior on the trans. Why because I've been having an issue with getting it in 1st and 2nd gear once it warms up. I've already installed new slave and master cylinder and fluids to see if it would help It didn't . So after dropping everything out and pulling the flywheel I stuck a straight edge on it and it's flat no convex at all. So I'm wondering sense it seems to have been resurfaced could this be part of the cause of my shifting issues. I know the PO had the clutch done right before I bought it and that's when the issue started. Someone please in lighten me on the issues with resurfacing the fly flywheel. Thanks

I doubt that your clutch or the flywheel is the issue. Jeep flywheels should not be machined, but that in and of itself should not effect shifting into only two gears only when it's warm. I think your issue is more likely in the transmission. Probably syncros. Have you tried draining and putting fresh lube in your transmission?

Yes that was the 1st thing I did. After pulling the tranny stuck a bore scope down every hole I could to check inside everything looks really good from what I can see. The previous PO had the clutch job done because the pilot bearing went out. I'm hopeng that who ever did that and the clutch job just didn't get every thing lined up. I tried to insert the alignment tool in before removing the clutch and would hardly insert it took some muscle. Also I'm not getting any grinding it just won't go in once warmed up.

Sorry, still think you're barking up the wrong tree. Whether the engine or transmission is cold or hot wouldn't really effect clutch operation.

Yea I think I'm just in denial I really don't want to drop the money on a new tranny. But atleast if I do everything else will be new. Just figured I'd try this for $hits and giggles. I'll keep everyone updated once all the parts get in and put back togeather. Dang NV3550

Thanks for your insight Water Dog

It's pretty common for those cheep plastic clutch alignment tools to be difficult to insert, especially if they are brand new. I usually use an old transmission input shaft for alignment.

A clutch will be perfectly aligned when everything is re assembled and you press and release the clutch when the engine is running

If it's difficult to shift or has a slight mesh sound when cold they using Red Line 75W90NS - It's designed for racing, manual transmissions, and transaxles. Popular in Ferrari, Porsche, and Subaru transaxles

I agree with WaterDog, I scewed up and had my fly wheel resurfaced and after a couple thousand miles, no trouble. don't think its your clutch.

So I have an update. After dropping everything out here is my findings. 1. Flywheel was resurfaced so much that it was concave by .110. 2 when clutch cob was done by PO throw out, pressure plate was never replaced. So I installed all new LUK flywheel.pressure plate, throw out bearing, pilot bearing, clutch fork, master and slave cylinder. So I don't know which 1 of those was causing my issues but I've been driving the old jeep for 5 days with a bunch of stop and go all in this lovely 85 to 90 degree Las Vegas weather and she shifts like butter couldn't be happier

So the lesson here you are teaching the community here is that a really screwed up clutch plate will not disengage when warm making shifting very difficult.
