Hi all, I just replaced my transmission for a used one someone sold me on the this site. I can have the car in a halt and press the clutch all the way in yet when I try putting the shifter in 3rd it grinds :( I'm not sure whether it is a shifter problem or a clutch problems. Anyone dealt with this problem before ?

Visit AutoGuysLand to review auto diagnostic tool if you want to get one. Anyone dealt with this problem before ?
It might be a worn clutch or you may just need to have it adjusted.Take a look at this.

Air in the clutch line is a likely cause for failure to disengage. A worn out cylinder is another likely cause. Which slave cylinder are you using?

If the clutch pedal is fully down, and you are not rushing the engagement, then that is dispositive evidence that the clutch is not disengaging. It shows that the 3rd synchronizer is the weakest of the lot, but does not necessarily mean that it is unservicable.

Hi all thank you for input, as today I havent had a problem with it no more. I'm guessing it might be the clutch line. The problem isnt when I let go because I get a grind even before I let go of the clutch. When it's cold is usually the problem as I tested.

When I come in contact with the problem again I will pump the clutch to see if any difference. It worries knowing maybe the 3rd gear synchros might be going out but it's weird because the problem happens before i let go of the clutch even while parked.

Surely sounds like either a slightly bad master, slave or just air in system. My tvr does it in reverse when one of the hydraulic parts is going out every couple years since the seals aren’t happy with modern fluids.

How cold is it when the problem happens? What type of gear lube - GL4 I hope. Is the level proper?

I'm honestly not sure about hear lube, I have no idea what.lube my transmission shop used. I dont know much about the lubes I'm supposed to use. How do I check the proper level?

You should probably purchase the manual, many things are explained. IMHO GL 4 type fluid should be used in the trans. There is a fill plug and drain plug on the trans, location is in the book and very easy to find if you know what you are looking for, large hex plugs, one at the bottom and one forward. When the car is level and the fill plug removed the fluid should be level with the bottom of the fill hole.

Check the simple things first. The manual is a valuable resource if you want to know more and or perform work on your spyder. There are a few mistakes in it but IMHO very worth while. I have the manuals but I believe everything is available for download on technet ($$). If you do a search you will find info.

I had similar issue on my ‘03. Clutch was definitely worn at only 71k but 3rd was crunchy at various times. Took it to a local transmission specialist shop. Didn’t give him much for details, just asked what he noticed after a quick drive. He didn’t even leave the parking spot and told me 3rd gear synchro was likely worn and clutch turned out to be down to bare metal. I did some searching on this site and found several other posts about sporadic 3rd gear synchro issues. Had the shop rebuild with OE parts and never had another issue.

I have found it best to let a trusted tech find out what is wrong instead of saying "it runs bad, replace the XXXX". If only one gear grinds then the chance is higher that the problem is greater than just the wrong fluid or level. Still checking the simple things first is the best course of action IMHO. Throwing parts at a problem can get very expensive and frustrating. My first clutch wasn't worn out at 130,000 miles but since I had the trans out and it had wear the timing was good. It seems I don't abuse clutches, the Tacoma went 160,000 before replacement.

Let other members learn from this sad story.

Always, always have a professional evaluate your transmission purchase. Yeah, it's $100 or so and you'll have the best idea of future maintenance needs and an opportunity to fix an issue before the case becomes unbuildable.
