Transmission Crossmember

[YouGotSpooled]

I swapped in a R154 into my 87 non turbo supra when i did my turbo swap.. but the bolts on the transmission crossmember dont line up to the stock holes? The mechanic that did the swap modified it to fit.. but there is a really bad vibration now and I think this is the problem.

Is there different transmission crossmembers? From what I hear all of them are the same. Any ideas what this could be?

There is two sets of holes on the transmission where the crossmember mount can bolt to, make sure its on the right holes.

Is it possible that there is only one set of holes made for it to bolt up with the w58 on my pre-89 n/a?

It shouldnt be...it should mount right up. we put an 90T into an 87 NA, and no problems.

W58 and Auto crossmembers are very different so I'd assume the 154 uses the same cross member as the auto as they share the same slip yokes.

Doc: Pretty sure it's the lower one
(w58 is straight from memory)

Well wouldnt you use (common sense) the R154 cross member and not the W58?
I would assume its logical to use the member that came with the transmission. Cause are not all the Ma70 Chassis the same?

Looks like the Auto tranny brace is different from the R154 too.

Dub: Thanks I wasn't sure but knew the Auto one was different to the W58 one

Thanks for the help guys. I went and picked up an 89 crossmember off a r154. Its just toyota told me the cross member from 86-88 worked on both turbo and non-turbo.. and the 89-92 was different and worked on the turbo and non-turbo.. So I guess we will see if this one works.

Also.. The spline on the turbo driveshaft does not go all the way on the yoke.. there's a gap between the two "cups".. Im not sure why either..

Shaft is too short and will hammer the rear bush in the trans to death.

 

[YouGotSpooled]

Well how about putting the spline from the turbo drive shaft, on to the front half of the non-turbo driveshaft to make up for the gap?

 

[IJ.]

I'm confused here.....

The W58 slip yoke won't go into the R154 at all.

What DS do you have?

 

[YouGotSpooled]

I have the r154 driveshaft, but it does not go all the way on. I want to use the front shaft from my w58 driveshaft and switch the splines so it fills up the gap.

 

[IJ.]

Sounds like you have an Auto DS there (same yoke different length)

Never measured the w58 shaft so sorry can't advise on if swapping the yokes will work.

 

[YouGotSpooled]

Well I think its about 1" longer or so. It will fill the gap I have. Never hurts to try new things I guess. Lol

 

[IJ.]

Let us know how it goes!

I have several cross members they have arrows imprinted on them and "A" or "B" or "C" on them my brother is having a problem going from automatic post 89 to manuel W58 on his 7MGE motor he is having a difficult time lineing the cross member holes up i guess it is at least 1" off.
