Have an 02 Z28 with M6, only 1200 miles on the car. Was at HRP last night, and my first run seemed ok, but when I pulled off the track, would not come out of 4th gear. I sat there for a while trying to get it out with no luck. Finally took off in 4th gear to get the car to a different location, then few minutes later came out of 4th. Ran 2 more times no problems. Now the tranny sticks a little shifting out of 4th into 5th. WTF is going on? Anybody with any input please post a reply..

 

Blown 346,

I can't tell ya what is wrong but what did you run last night?

I have a 2002 M6 Hot Rod also and I am going to run today(9/14/02) in the brackets at HRP. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

 

There is problems with 4th & locking tabs for the sycro's + the lame 3-4 stock fork. Either way it's gotta come out.

I will tell I just got the car a few weeks ago. Only mods I have is flowmaster catback, MTI lid, and Hypertech 160. My best time last night was a 13.55 at 105.67. 60' was horrible (2.3). It is going to take some practice getting the car out of the hole, and some better tires. Once Im moving I have no problems powershifting through all the gears. Going today to pick up a GMAFS. Every week I will keep adding boltons. Once I get the car running good on motor. Im going to put TNT 150 shot on it.

 

Blown 346,

I do not powershift my Hot Rod and I have over 200 passes on her with no trouble. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Good luck with your Hot Rod and let me know when you head back to the track. <img border="0" alt="[angel]" title="" src="graemlins/gr_angel.gif" />

Coach

 

wrencher is correct , the keys for the syncro are probably bent a little bit..... must come out to be repaired <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" />

 

dude, the stock t56 is a piece of sh--. get a better shift fork and other parts from d&d performance in detroit mi. at this point their is'nt alot of aftermarket parts for the t56, but i hear a company is working on some better ones. goodluck.

 

d&d does have an aftermarket STEEL 3/4 shift fork. It's the most common one to bend. Normally bends on hard 3rd gear slams, but would affect 4th also. Most common fork to bend.

 

Thanks to everybody for the advise. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

It is your 3-4 shift fork. There are some plastic tabs on it that work with the synchros. I just took mine out and had D&D do mine last week. Cost is $250 in labor plus parts. Here's what they charged on mine:

1 - 2.66 2nd Gear - $149
1 - 1 to 2 Synchro assembly - $149
1 - T56 Synchro rebuild kit - $229
1 - Steel 3 to 4 Shift fork - @49
Michigan Sales tax at 34.56.

Grand total of $860.56.

I had them go over it and replace anything that needed it. The 2nd gear and 1-2 synchro need to be replaced because the synchro mess was a little chewed up. Not terribly bad, but worth replacing while they had the transmission.

I will say that D&D is a first rate shop. They just moved into the new place and I was amazed how clean and organized it was. I had my trans dropped off this last Monday and requested that I can pick it up on Thursday barring any unforseeable issues. They tore it down and gave me a call on Wednesday. Told me what needed to be done and when I showed up on the way home from work Thursday it was there waiting for me.

Absolutely one of the best experiences I've had with getting service work done! When I picked up the trans it was soooo damn clean it looked brand new. When I dropped it off it looked like it had been to a war and back. My dad saw it and thought they gave me a brand new trans! I got it into the car last night and the shifting was a ton better than it was when I picked the car up the first day! Shifting is very firm and solid.

Anyway, just a quick hint on taking the trans out. Just remove the 8 bolts from the trans to the bellhousing. Don't even mess with the bellhousing. That's all they needed.

To give you an idea as to how much stuff was replaced, here are pictures of the parts that came out of the mine. Notice the picture of the shift fork. In one of the photos you'll see a little black piece of plastic. That's the tab that broke, what a POS! The other tab also broke and the trans ate it! Couldn't even find that tab in the fluid.

Mines being replace right now. The retainer was shot. It's the 3rd time the trans has been out with only 5K mi on car AND no power adders.

 

I have had the same problems with my car. It stuck in fourth just like you described. I took it to the dealer and they replaced the 3-4 syncro?? but not the shift fork. As soon as I got it back I noticed that it would grind 3rd if shifted quickly regardless of rpms. It was also making a whining noise in 5th and 6th gears. I took it in again and just picked it up today. They replaced the 3rd gear syncro, shift fork and a few other things. Well 3rd shifts a little better but it now feels notchy and it still makes that sound in 5th and 6th. I am taking it back as soon as I can and am demanding a new tranny I don't wan't them to ever try to fix something on my car again. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> Oh yeah my car is a 2002 Z28 with about 8000mi.

Yep I am having the same problems with my tranny right now, after only 4,000 miles on the rebuild! <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> I am getting a new tranny but I want to put in the steel shift fork. Anyone have a contact for the D&D Transmission place??

Anyone that answers the phone will do. I dealt with Steve on the phone and Joe at the shop.
