Default Tremec 5 Speed

I'm installing a tremec 5 Speed in my 80 and have an issue with the top pass side bolt into the bellhousing. Can't get a socket or wrench on it. Also need to move the tail over to center it in the tunnel about 3/8" toward the driver side, but doesn't move real easy. I don't want to put a lot of tension on the mount. Any thoughts?

I've not installed that particular tranny in a Vette but it might help loosing the motor mounts and sliding the engine a litte forward to get the bolt started. You shouldn't have to disconnect anything from the engine but I'd pull my fan just for safety.

I used grade 8 Allen head bolts for the tranny to bell and bell to block. Loosen the motor mounts as stated above (the long through bolts) and it should give you enough play to slide it over...if not, just !

I would never do a transmission swap without a removable crossmember or at least a section that comes out. With the crossmember removed you can drop the back of the motor or easy working on the bellhousing bolts. Make the crossmember removable and in future you won't dread working/removing a transmission so much.
A wrench from the top works.

I had to push my transmission mout over towards the passengers too until the yoke on the trailstock almost hit the tunnel. I just pushed it over and drilled the holes for the transmission mount. Never had a problem in the 4 years I have run the 5 speed.

I like the allen head screw idea. I don't know why they don't sent them with the kit cause the bolt thing just isn't happening in any way shape or form. I'll pick some up in the AM. Then I'll try the motor mounts next. Thanks

Actually the 80 has a removable cross member. The issue is clearance between the trans it self and the bolt. The head of the bolt, & the ribs on the trans won't allow a wrench to turn. The answer sounds like the allen head screws in place of bolts. Moving the motor is actually an issue with my side pipe exhaust I think. I'm going to unbolt all of that and see what happens when I move the tail over. Thanks

I'm sorry. I misread it. Ford was difficult. I remember the mustang had this problem. The head of the bolt almost touched the housing. Yes a cap screw would take up less room. Even worst was when they put a little head on a larger bolt resulting in rounding out the flats.
Sorry agian

I had the same problem with the bolt but seemed to manage using a socket and an open end wrench.
I hope this isn't a Keisler kit or you're in for a lot of surprises. If so i was the first to put one in an 80, according to Keisler, and it was nothing short of extreme pain.

Maybe you could get to it using a ratcheting box end wrench. I was able to use a socket on my setup. Hopefully, you will get it tomorrow.

Crow's foot on the end of a ratchet and extension. You can get them at Sears.

Wrong size, but you get the idea.

Yes you were the first...right after mine

The top right bolt is a pain, even a socker head is no walk in the park, did they send you a modified xmember ?

Funny you say that. It is a Keisler, So far it has been painfull. I also got or should say am waiting for a Hydraulic clutch setup. That little actuator on the front of the trans was fun to say the least to get into the blow shield. the rear mount isn't looking like a winner either. I have the cross member in place with the tail sitting on it for the moment till I can move it over a little more. And have it stay there when I let off the pry bar. Then we will see what the mount adds up to next. Looks like I'm in for more fun. The when the master comes I get to try and do the hose thru the fork hole. Though I can't even imagine having the hose on first and try to get that all in at once.

Modified cross member?????? No all I got was a mount to be bolted on that doesn't look to promising. I cut off the old one and haven't decided what to do with the new one yet. Does it work with the 80 or did you do something else?????

I often wondered how their no mod-direct bolt in package worked in the 80-82's especially the xmember. A while back a member here with an 80 had to ship his xmember to them for a modification. I had to mod my xmember for the ROD. It was the most time consuming part of the installation but turned out really well. From all appearances it looks stock. I could be wrong but I don't see how a mount could just be bolted on and work correctly. I also don't know how you guys do an installation such as this under floor jacks. There's no way my old bones and muscle could attempt this.

I can remember partaking in a few similar experiences when I was much younger.
