   When you have to shift slowly and deliberately , it is usually the shifter on a T-10 . There aren't any rails or detents in the shifting mechanism.  There is only a small interlock pin in the cover and is not the source of your problem.

Peter,

Your problem is probably different than the problem I had but I had similar symptoms.  Mine started out where I could net get it out of reverse.  I found that by shifting a certain way I could fairly repeatably get it out of reverse. After a while things got worse and I was having a hard time getting out of 3rd an 4th back into 2nd and 1st.  So at this point I decided I needed to dig in and see what the issue was.  After much exploring and trouble shooting I determined that I was missing the two washers that compress the rubber grommets used in mounting the shifter to the shift mechanism.  I had replaced the rubber grommets about a year ago and did not realize there was suppose to be washers.  When those grommets wore out very prematurely I could tell the hex head of the shoulder bolt was doing a number on the rubber.  I bought a hardware kit complete with washers and got new grommets and my shifter has never felt better.

Thanks Gents

The shifter mechanism has now been changed and the shifting action is lovely. Nice and tight and direct. When the box is playing ball it shifts as nice as any other. Its just now and then that it sticks in 2nd and won't come out until BANG and it pops out and returns to shifting nicely.

Also. just had an email from the guy who drove it after me and he said it tried going into reverse a few times when shifting into first

Does anyone have some TNT?

Cheers. Peter

Hi, I agree completely with Corey. I had no washers on my shifter handle to shifting mechanism and it felt so indirect and barely went into gear. The rubber grommets where shot, initially I replaced just them but no real change. I could see the handle pivoting and moving on the mechanism. 2 lock washers later and she shifts like a dream.
I am glad you sorted out one issue. But all t10 owners with original handles need lack washers

Cheers

The washers should be thick flat washers (NOT Lock Washers!)   with same ID as the OD  of the locking special hex bolt.  if the shifter bolts bottom out the shifter will flop around - add washers until it gets tight without the bolts bottoming out

Yes the flat washer serves two important purposes. First it distributes the load on the grommet more evenly than the smaller hex head of the bolt. Secondly sense the bolt bottoms out on the shoulder not the grommet the washer compresses the rubber grommet far more than without it making the grommet far stiffer. This is why it is also the important to have the correct fairly thick washer.

Just to clarify, even at my age I don't have a floppy shifter :-)

that is one sexy bit of kit

I havenít worked on it today but am thinking either the synchro is getting stuck to the gear or there is a mechanical interference on the 2nd gear rod

   look at the linkage carefully.  IF you still suspect the synchro , pull the side cover and try to move the slider by hand in and out of second.

Update

Got the car on a lift, got it stuck in gear

Lifted the car and looked underneath.  Everything clear, nothing touching the levers or rods.  So not a interference issue

Removed the rods off the shifter, shifter easily moved so not the shifter,  levers on trans wonít move

Gotta be inside the trans

Sometimes itís jammed solid others itís like the lever moves but definitely rubbing inside

Trans is with the guy who built it now for diagnosis

thanks for sticking with me on this
