Re: IML: transmission woes

["mike and linda sutton" <mikanlin62@xxxxxxxxxxx>]

A couple people wrote in today with transmission woes,  which before I go 
any further I have to preface with a couple things....first, any advice I 
give applies to 62 and later aluminum torqueflites as I have no experience 
with the older ones.  Secondly, I cant actually see your car from here no 
matter how hard I squint so this is only advice based on practical 
experience , your actual transmission problems may vary.

Someone had no reverse...BEFORE you get a rebuild and all that, find a shop 
that is well versed on these transmissions and have them drop the pan and 
see if the low reverse band has broken, or the low reverse servo has flipped 
over in its bore or if the band anchor has came out.  One thing I didnt 
catch in the initial email was if manual low still worked or not, often 
times people seldom put their car in manual low and never check that in the 
diagnosis.  If...if mind you...the low reverse band or servo has failed and 
the rest of the trans is intact, that would give you a no reverse condition.

The other item was a leak from the rear yoke, the slip yoke for the front u 
joint , if I read correctly.  I believe the yoke has a plug inside of it, 
similar to a freeze plug,  that may be leaking. Normally there is not a lot 
of fluid in the rear of the trans,  the tailshaft housing doesnt have much 
back there that requires oil under pressure except the governor and the rear 
output bearing just gets splash oil, there is a drain to allow whatever oil 
that gets back there to go back to the pan.  So if the transmission oil isnt 
coming from around the rear seal but it is leaking from the yoke itself, 
check the yoke for a disc type plug inside of it.

Hope this helps your mechanic
