buZy Posted May 5, 2006 Share Posted May 5, 2006 Hearing groaning noises and sticky shifting added up to $1300 in repairs. Ouch! The photo shows where the countershaft drive end broke and 5th 6th reverse worn syncs. The guy said it was lucky the broken piece did not smoke the whole gearbox. Who ever build the car it is safe to say the trans went though abuse in past, along with many other things. Posting as to ask the question is this a common failure area? Not to worried really as I don't do drag launches or road race the car. But still very curious as maybe someone with greater experience would know more about this. Thanks all!

jbc3 Posted May 5, 2006 Share Posted May 5, 2006 Which countershaft went? The 5/6 one or the 1-4? Looks like the 1-4 one in your pic. I have a good 5/6 countershaft. If the reverse synchro is worn, don't replace it.... flip it and use the other side. The T56 does not use a one sided reverse synchro. Hard to say if it was abused. Hard shifting can break the small synchro clips that hold each synchro in gear. If one came out (which they do on occasion) and ran thru the tranny before it was trapped by the magnets... who knows what damage it could have done. Loose all 3 clips on one ring and the tranny will try and go into two gears at once..... then your countershaft will be shreadded. I have seen that a couple of times.
