904, manual valve body, "drag free".
Behind a mild stroker. (Iron heads, flat tappet cam) built by a reputable shop.
Its always had a flare on the 2-3 shift when shifted at wide open throttle. A search of this forum says incorrect kickdown linkage adjustment can be the culprit. However being Manual, it has no kickdown assembly fitted.
I hit up the shop who built it, who said we should pull the trans down and inspect the forward clutch pack. (Oh and that the 904 is a light duty box not suited to HiPo applications)
Although the trans was built a good few years back now, it's done very few miles/passes.
I watched a few videos on youtube. A bloke pulling one down. He was from some shop, who I found on facebook. I blew some smoke up his arse about how great his video was before asking what he reckoned. His take was the preload on the forward clutch pack was wrong?
Anyway, yesterday I went to a book shop and ordered a book about rebuilding torqueflites. And today the trans came out.
I've probably mentioned this particular problem before. But I thought I'd ask what the F.A.B.O. hive mind thought once again since the time to fix it is here.
Having a huge flare on that 2-3 shift blows. Its gotta be adding a tenth or two to the E.T. And my sphincter tightens something fierce when the engine revs up like that. I actually thought id been over selecting, and hitting N to be begin with. It still has the column shift which is a bit clunky. (Soon to be a B&M megashifter, which should transform what the car is like to drive)
Any suggestions greatly appreciated.
Bart.
