Transmission spacer

I read somewhere on this forum(?) that there is a steel spacer between the frame, and the transmission crossbar. I'm just about to put my tranny back in and there are no spacers on it, nor can I find a source. Is this a part that was on my jeep? ('65 cj5 134) Could I have read it on April 1st?
Thanks!

 

They are 1/4 inch spacers and mine has 2 on each side between frame and crossmember. I do have a V-6 in mine.

Yes, I have never seen factory spacers used with the stock T90 transmission. However, whether or not you need them depends on your rear driveshaft angle which is typically much steeper with any aftermarket lift springs. There should be a number of threads on this site addressing that. Very easy to make the spacers out of steel or aluminum bar stock.

I do have a t-90! Perfect, that's why they're missing. Thanks all for the replays!

 

I have a '62 CJ-5 with the T-98 in it but it also has a lift kit. To keep the angle on the driveshaft from being too steep, it has spacers about 1" thick between the cross member and the frame. It wouldn't hurt to put some in if the rear driveshaft angle is fairly steep on your vehicle. I had a Chevy S-10 that had double cardan joints in the driveshaft because the angle from the rear of the tranny to the front of the diff was too steep for regular U-joints. I had beefed up the 4.3 liter V-6 that was in it. With the increased power and the crappy angle of the truck driveline, these joints would wear out quickly and they were hell to replace!! I finally went to a driveline specialist and told him of my issue and asked if he could build a one-piece drive shaft for me that could work. He said he very well could, but when he did, he told me I needed to get on a website called "JTR" (Jags That Run) and order an alignment kit which consisted of pieces of metal. They were shims. Two were to lower the back end of the tranny, one was for the center bearing, and the last two were to be installed to tilt the rear axle slightly to line up everything and eliminate the need for the cardan joints. It was great!!! No driveshaft whip under power, no vibration, etc. Too bad Chevy engineers were clueless. Could have saved a lot of trouble. I understand Dodge 4X4's use these in their trucks somewhere in the driveline. Just one more reason not to own a Dodge...

 

eti engineer,I'm not saying you are wrong, I think every conversion is a bit different. Engine mounts and springs all come into it so it, changes the angles. Back in the '70's I did a v6 in my MB. The only reason I dropped the crossmember was to get the extra room for the T90 to the body, it ran faster than the speedometer went with no vibrations. I did go out an look at both of my Jeeps.
(In the rain, youre welcome). The 3B with with the V6 and 1" lift has no spacers but the Commando V6, manual. has about 3/8" of spacers on it

 

No problem. I agree that every conversion has its issues. As I mentioned before, I put a 280Z engine in a 530i Beemer. That was an easy job as far as alignment was concerned because of the fact that the differential doesn't move, since it has independent rear suspension. Jeeps are obviously a different animal. Your '65 Jeep sounds like a good line-up as far as the drivetrain is concerned. I would imagine the OD is a good thing with the V-6 in it. I will decide what I am going to do as far as the F-134 is concerned once I get it off-road under its own power and see how it performs. If I do go the V-6 route, I will probably spring for the OD, but from what I can see, most of the guys in here have stated they didn't gain any top end putting the OD on the F-134. They did it mainly for gear-splitting. My Jeep is a bit strange in that it has a T-98 in it and the D44 has a 4:27 ratio. I have the Warn hubs. Wouldn't have it any other way. Your gonna love this one, though. The guy who had the Jeep before me, put wood spacers between his cross member and frame. What was he thinking? I just got done rebuilding the tranny and xfer case and got it back into the Jeep. Today, I am going to make the spacers out of aluminum stock and finish bolting it all together. I may actually see the wheels spinning under their own power today. I have it on four jackstands so I can do that. The brake system is in need of new lines and hoses, so the rubber will not hit the road for a while yet. Have a good day...

 

For eti engineer. Wood spacers were factory installed on my 66 Tux between frame and cross-member. Several other members here had the same thing. This was used on the 225V6 with T-86AA. Don't know for sure about other engine/transmission applications.

I do know that without the spacers, my clutch tube was miss-aligned (horizontally) and made the clutch hard to push in.

 

My 66 CJ-6 with the Perkins and T-90 also had/has the wood spacers from the factory between the frame and cross member.
