gvincent Posted December 21, 2006 Share Posted December 21, 2006 Hi I have the JTR book and it says to remove the old transmission mounts, I also did an extensive search and it seems most of the T56 installs have been into a 240Z tunnel, I know the 280Z has more rom and was wondering if you all removed the old mounts as well. This post got me wondering: Originally Posted by speedmon David, Thanks for the picture......that is so cool, the way that fits right in. Did you have to make any changes to your trans tunnel or did it slide right in? On 1 Tuff Z's album, which is almost an illustrated step by step guide, he removes the crossmember ears......is that what is referred to as the trans tunnel mod? Different year 240's have different style ears for the trans mount. I did remove the trans mount ears but after fitting the trans they may not have needed to be removed. We did need to do a little pounding in a few areas to gain some clearance. __________________ ENJOY THE RIDE!

So those of you who have a T56 in a 280Z body how much tunnel massaging did you have to do? Remove the monts completly flush with the tunnel walls? Can you leave the band that goes around the top? Where in what locations did you find you have to do some clearancing with a BFH or was there really a need to? I will probably end up with an LT1 or a Stroker motor since my LS1 deal feel through. (Long story I will post elsewhere) Thanks, Greg Quote Link to comment Share on other sites More sharing options...

The only place I had to use the BFH was for the Back up light switch. It was pretty easy. Every thing else just slid right in. mike Quote Link to comment Share on other sites More sharing options...
jbc3 Posted December 21, 2006 Share Posted December 21, 2006 Cut the stock mounts out (tranny mount ears). 1 minor dent is a must, Clearance where the back-up light plug goes in on the passenger side. The other is only if you plan on taking the bellhousing off while the engine is in the car; on the passenger tunnel where the second from the top bellhousing bolt goes in. Otherwise I don't believe I did anything else except open the shifter hole up a little. Jody 1 Quote Link to comment Share on other sites More sharing options...
gvincent Posted December 22, 2006 Author Share Posted December 22, 2006 Thanks Guys, I was not sure, I think I am reading too much and need to pull the motor and trans out and get started on it! Do you have pictures of your tunnel mods? So you left the band that goes around the top of the tunnel? I would like to leave that tunnel reinforcement in if possible.

1 tuff z Posted December 22, 2006 Share Posted December 22, 2006 greg, i found that removal of the 'ears' was necessary but leaving the band the ears attached to is ok. yes, you'll need to massage the tranny tunnel on the pass side to clear the [i think] reverse connection area. there are 4 'prongs' that protrude from the tranny. i believe they were put there to protect the elec connection.

gvincent Posted December 22, 2006 Author Share Posted December 22, 2006 Thanks 1 Tuff Z, I thought I could get away with keeping the band but wanted to double check with somebody that has been there and done that. I might grind down the prongs on the tranny before I install, The less time under the car swinging a BFH the better as I see it. It is a bit harder for us old farts to be laying on our bad backs swinging a BFH, the fewer trips I have to crawl under the car the better!

1 tuff z Posted December 22, 2006 Share Posted December 22, 2006 greg, i believe you could grind the ears a bit but will then need to modify the molex connector. probably remove the wires and plug them each individually to their respective connectors. the stock connector is pretty tall-i notched the connector at the wire end then placed the wires in the notches, creating a 90 degree angle with the wires which allowed for a bit more clearance.

gvincent Posted December 26, 2006 Author Share Posted December 26, 2006 Thanks everyone for clearing up the mystery. I will cut the ears off, gring the prongs, and make my own right angle Molex connector. I won't be separating the bell housing from the transmission. I think this covers it all, I don't want to have to pull the engine and transmission in and out too many times. Thanks, Greg Quote Link to comment Share on other sites More sharing options...
1 tuff z Posted December 27, 2006 Share Posted December 27, 2006 greg, don't forget to post pics as u progress-for the rest of us-and...those who follow. Quote Link to comment Share on other sites More sharing options...
gvincent Posted December 27, 2006 Author Share Posted December 27, 2006 Yes, I have digital camera in hand and plan to document the whole project, I will post in my picture gallery and in the "Projects" postings. The next group of pics will be the removal of the L6, 4 speed, Driveshaft, exhaust radiator etc. Then engine bay prep. Thanks all for the help so far. Just getting started, Excited!

twoeightythreez Posted December 28, 2006 Share Posted December 28, 2006 I'm glad I didn't have to use a BFH on my Z yet (though I used one to make parts for it) Quote Link to comment Share on other sites More sharing options...
