[ba] 4kQ Tranny troubles

... it does sound like you need a clutch ... but before getting too caught
up in a new tranny make sure the shift linkage hasn't come loose somewhere.
There are several places where a problem can develop ... where the linkage
attaches to the shift rod is the primary area to look.  The ball of the ball
and socket joint can get loose, and there are several plastic parts which
deteriorate ...

The tranny in the 4kQ isn't that much different from that in a TQ, so with
the reduced horsepower IME the trannys on 4kq's are virtually indestructible
... unless perhpas you are low on lube.  Even with that they are pretty
robust ... I bought an '85 4kQ with over 200K miles ... when I drained the
tranny and refilled with Redline it poured out from the front drive seals
... who knows how long the car was run this way before I bought it.  I
changed the seals and topped it up ... the car is still running fine a few
years later ...
