  • T56 install problem

    After check and rechecking at least 6 times, I still had a problem getting my trans to fit completely intothe bell housing. It goes in almost all the way except for the last 3/8 inch or so. No matter what I tried I could NOT get it to seat flush. I could, however, pull it together with the bolts.

    I read another similar post on LS1TECH and apparently this is OK.

    Anyone have any thoughts?

    your clutch isnt properly aligned. I went round and round with mine like this, (it sucks i know) until i went to autozone and rented a steel alignment tool (opposed to the plastic one you get usually) and then it slid right in. you can force it with the bolts, but i really dont think thats a good idea.

      Yep, its not aligned and caching on the pilot bearing. The plastic tools suck.. I have a broken input shaft coming to use cause I have had many issues with the plastic ones

          So here's my plan: Since it went together physically without a TON of pulling pressure, I want to have my wife push the clultch in (engine off) while I turn the output shaft with the trans in gear. My thoughts are that if the input shaft is running freely it should turn without much trouble, and if it won't turn or turns really rough I need a new bushing. I really want to verify this fit before reassembling the whole car.

          And yes I did use the crappy plastic alignment tool.

          Thoughts?

            Ok here a method i use when nothing seems to want to go together. bolt the trans up so its as close as you can get it without using the bolts to pull it in leave a bit of slack. Step on the clutch a few times to align the disc and the input shaft with the pilot bearing and sort of tug/push jiggle on the trans a bit to line it up makeu sure its well supported and parrallel at the 2 mating surfaces. If that doesnt work head over to NAPA autoparts and pic up one of there clutch alignment tools kits. The other thing to note is that the Clutch pilot tools should easily slide into and out of the clutch and pilot bearingif it does not you are not lined up. the other thing you could be fighting is the throw out bearing itself but opening the bleeder can lead to a pandoras box of clutch bleeding.

              Right but this is an LT1 so there is a clutch fork and no hydraulics in place at this stage of the install.

              Come to think of it though, the plastic clutch tool went in and out but was a little sticky, meaning it didn't pass through absolutely cleanly....

                Oh sorry forgot was an LT! we are dealing with. Yeah if the tool is "sticky" the clutch isn't aligned well enough to insert the trans.

                  My trans did the same thing. . . The easiest and most effective solution, IMO, is to do what Sean (CollinsAutomotive) suggested. That is what I did, and I know mine is a T5 bolted to a V6, but I was having the same problems, and I think you may be able to fix it relatively easily by doing that. I bolted my trans up as close as it would go without forcing it, pushed in the clutch, and heard a faint thud under the car, I got under and looked, the trans slipped right into place. I pushed it the rest of the way in by hand, bolted everything back together, and went cruising for the rest of the afternoon to break in the clutch.

                        UPDATE-

                        Went out after dinner tonight, trans in gear, no turning of the tailshaft as expected. Had the wife depress clutch pedal, smooth-as butter turning, NO drag. Think I'm OK.

                        Gonna throw out that plastic alignment arbor.....

                          Yeah, on an lt1 get the splines engaged and push the fork while someone slides the trans the rest of the way. I had to do this last week with a twin disk cause the tool sucks

                            Think I am gonna search eBay for an input shaft for next time.

                            Have to say it though, the Fords are easier. Although the Mustang I had had 4 bolts holding the T5 to the bellhousing, versus eight on the Poncho. Which is better? I dunno.
