Hmmm..... Sounds to me that you have something there. I'll check it out next 
time I look at
the gearbox. May I presume that you are speaking of the wiper gearbox and not 
the transmission? It makes sense to me then and could be the problem - though 
minor - with my wipers ending in the upwards position and having to be 
juggled to get them down to the 
parking position.

 Yeah, heating and bending is the last thing you should be thinking 
 about doing now.
 
 Think about this:
 
 The motor just goes around and around, continuously and at a constant 
 speed.
 
 The linkage changes that motion into a reciprocating motion that 
 gives some number of degrees of motion. If the amount of degrees 
 gives you the right pattern for your car then this much is fine.
 
 If the swept pattern on your windshield is correct but the blades 
 park in the wrong place, then the problem is NOT that the pattern is 
 wrong, or that the blades are wrong, or that the arms are wrong. It's 
 just that the pattern gets stopped at the wrong point.
 
 So.... What determines where it stops? It's the parking switch in the 
 gearbox. If you want it to stop at a different place you just need to 
 rotate the actuating arm (that's the arm that goes round and round  
 and that fits on the gearbox output shaft. That arm is in a certain 
 position when the wipers are at that position on the windshield where 
 you would like them to park. So if you loosen that arm on the gearbox 
 output shaft and rotate it so that the wipers are in the parking 
 position when the gearbox parks then you get everything that you're 
 interested in to happen at the same time.
 
 It's really simple, but you may have to do it and see it for yourself 
 before you understand (and believe) it.
