Transmission trouble, need help.

[Rubent70]

I have searched the forums and can not find a problem similar to mine.
I have a 5-SPD spyder and the issue I'm having is only with my forward gears.
In first or second gear with the hand brake fully engaged as I begin to let off the clutch the car leans forward (normal of curse) but once it starts to lean forward there is a loud grinding/popping noise as if something isn't grabbing right, inside the tranny.
I tried this in reverse and it's perfect no problems.
Again this happens with first and second gear.

I put the car up on jack stands and removed the wheels and it spins freely in 1st, 2nd, and even 3rd no tranny noise.
Placed the wheels back on and dropped the car and again same issue. Lurches forward in gear with a loud grinding/popping noise.

Does anyone have any clue as to what this may be or should I just start sourcing a replacement tranny?

Thanks in advance for y'all's help.

You never know could be a cable issue or tranny if your unsure i would go ahead pull it out and have it inspected you may need a simple rebuild, again i would start there if you dont know the condition of the transmission.

I'll probably drop it next weekend and run it by a shop to have them check it out.

Crawl up under the dash and locate where the clutch pedal rod is located. Pull the little black bootoff the silver part and tell us what you see. I ssuspect a clutch master cylinder leak
Report back with your findings.

 

[Rubent70]

I will crawl up under the dash first thing in the morning and report what i see

Update: I pulled the cap off and it seems to be pretty clean. There was some fluid on the cap and a little underneath the cap but not a large amount at all.
Is this normal or should it be completely dry?

I did some search and most people say not to use an auto parts store brand master clutch cylinder, are they really that bad?
I'm thinking about ordering the OEM master clutch cylinder from extreme psi should I order the OEM slave as well or is that fine to pick up from auto zone?

Does anyone have any suggestions as to what I should check next?

Maybe your axles? When ever weight in on them they grind and stuff? But when no weight is on them no popping? Could be the master cylinder also. Let us know!!!

 

[Rubent70]

The axles are fine.
I had removed them to reboot them cause they were torn to hell .
When i placed the axles back in I turned them by hand and they both turned together fine.
So I'm assuming they should be good.

Did you check your fluid in the transmission? Right before i blew mine up i had problem like this. Also you might try and adjust your clutch maybe its not fully engaging and has chatter. I have also seen this on clutches.

I will drain the transmission tonight to see how the fluid looks.
I'll try adjusting the clutch this weekend or after i get the master cylinder and slave replaced.

Has anyone used the Exedy CMC(clutch master cylinder)? I found it amazon for $30 did some searching and the reviews have all been good so far. Just wondering if anyone here has some insight on this product.

So far it doesn't look to good.
Drained the oil and attached is a photo of some of the shavings I found.
Can anyone point me in the direction of a good rebuild kit?
Thanks again for all the help.

 

[Rubent70]

Changed the oil and drove it around the block.
Still makes the popping noise when taking off in first or second.
Found some metal chunks in the oil, pic above.
I have no problem shifting gears at all and there's no slipping under WOT.
Any ideas?
I will be replacing both the clutch master and slave cylinder this weekend.

 

[Rubent70]

Ok so here's the latest.
Replaced clutch master and slave this weekend and still have the same problem.

To clarify the problem as I begin to take off in 1st or 2nd the car makes a loud clacking sound coming from the tranny, once rolling its gone and no issue or tranny noise while switch gears at all it actually shifts quite smoothly now.
I just have no idea what to check next.
I will probably replace my cv axles soon to see if that makes any difference.
Any suggestions would be greatly appreciated as I've hit a brick wall with this issue.

Save your money on buying new axels, it wont fix the problem. you have to open your transmission and check out where those metal chunks came from.

 

[Rubent70]

Turns out the cause of the nasty clacking sound was my cross member. Some of the bolts were loose.
