What am I doing wrong? Crossmember

[Mattheyew]

Evening everyone! Apology in advance if there was a better place to post this or if its been discussed a million times in a place the search function doesn't reach.
I have a new to me 86 MC SS with a 305/350 combo. I got the car through a trade and its new territory for me, especially the automatic portion.

My questions:
Am I doing this forum thing right?
Why can't I get the crossmember to work, previous owner said it should bolt right up.
How do I know if the kick down cable is set up correctly, if one is installed.

That crossmember is for a th200r4 or ath400. The th350 has the mount a few inches forward. This is the style you need for a th350 http://i187.photobucket.com/albums/x290 ... member.jpg

Thank you for the picture. Any chance of modifying the piece I have to work?
If not,
Did the MCs come with a th350 and thats where Ill find that piece or is there a list of vehicles I should look for at the JY.


Any insight on the kick down?

The mc SS from 85 up is 4spd auto if I'm not mistaken. I think 84 was 3spd.

You can get one from any 78-and up three speed auto malibu, regal, olds cutlass or pontiac gp or lemans.

Where are you located?

If you didn't know, Jegs sells a dual exhaust crossmember for $129 with free shipping, part number 41050. The way I look at it, no hunting for a stock one at junkyards, fighting corroded bolts and especially not having to worry about modifying a stock one if you go with duals down the road. I'm a big fan of saving time and avoiding aggravation.

Im sad no one has tried or been successful at modifying cross members. I guess Ill order the jegster and while waiting seeing if i can chop the member i have to work. I always love finding free ways to make things work

I have a 1985 Olds 442 and swapped out the 307/2004R for a Chevy 350/700R4. I purchased the Jegster and their true dual w/ chamber exhaust. I haven't yet installed the exhaust (due to a motor mount issue) but the crossmember fit perfectly. I can also tell you (and I'm sure someone will pounce on me if I'm wrong), but I believe the 2004R, which was original to your car, is the same length as a TH350 short tail housing, and the 700R4 is the same length as the TH350 w/ the long tail housing. So, it sounds like you may have a TH350 w/ the long tail housing. I'd have someone who knows transmissions look at it. Also, if you can do so easily you could take the overall length measurement and call your local transmission shop and ask them the length of a 700R4. I would do this before you order the Jegster. If you order the part for the 350 and you have the long tail housing version, you'll be no better off than you are now. Another thing, is that the Jegster is a double hump version so you can run your factory exhaust or a true dual. Good luck.

@whatupg, so are you saying that a cross member for a th350 will work on a 700r4? I have a 700r4 but a 3sp cross member. The mount is like 2-3" to the right. I was gonna try to modify it but.
