Default Tremac 5-speed

Has anyone installed a Tremac into their 68-72 Chevelle? I'm having all kinds of problems with the cross member and going to have to do major tunnel cutting.

I have one in my 69. I had to cut the tunnel from the firewall all the way back to basically the front u joint. I think my floor braces are saggy, as my driveshaft is way up from where it was with the pinion angle correct. Even with the TH350 I had, the front u joint would hit the floor with a few people in the car, so mine has more to do with it than just the trans. I have new floors, but I stupidly didnt replace the floor braces, I think I should have.

Here is what I have so far, the sawzaw went right through the sheet metal like butter....I'll have to do some massaging to the replacement metal they sent me as it does not cover what I had to cut. As you can see I still have some triming to do.

It's about the same length as the cross member only needs to be moved about 1.5" back. It's the height that is a lot more. I will take some pics when I get home of the new metal they gave me (it's not installed yet) it is actually pretty nice.

Default I'm screwed on this one

I just checked my runout of the bellhousing and found I have a .020" runout and now I have to remove the dowl pins and replace them and it does not look like it's a easy job. I can't believe .020" would really effect this transmission.

Better news, it's only .010" as I forgot to divide by 2, but it still is over tolerance and need the dowel pins changed.

Did you by chance try loosening up the bellhousing a bit and moving it in the direction it has to go and re-tightening it? I know with my lakewood scattershield their was enough play in the dowel holes to move it a few thousandths in one direction or another. We dialed mine in to .001 out pretty easily.

Jeff,

I was thinking the same thing on my way to work this morning, that all I have to do is push the bellhousing up, as the biggest varation is at the bottom of the hole -.015" ...thanks for the validation on what I was thinking doing as well.

Well it's official "I can't get the dowl pins out to replace them so I can get my 5-speed in" I'm going to have to call a couple of places on Monday to see if I get the car up to them if they can get it out...if not, the motor comes out and I will have to drill them out. I can't drill them with the motor in the car.

I'm thinking this is the worst idea I've had in a long time putting this transmission in as it has be nothing but a pain in the ass.

Ric, anything you try to do on these cars is a pain in the ass. I finally got my dash installed and all the gauges working. I started on this a month ago. Haven't put the dash pad in because I'm not too crazy about the color. It's supposed to be the same color as the dash but vinyl paint instead of hard plastic/metal paint. It's not even close, it has so much red in it.

Anyway, you'll get there, kick back and relax a bit. Come on down to Bakers tomorrow, Ray and I will be there, supposed to be a nice day.
