Trans. Stuck in Low Gear
Year: 1986
Model: Vanagan GL
Engine Size: 4 cyl
Auto/Manual: Automatic
Mileage: 103,658

I purchased this Volks Vanagan because it was straight and clean with original milage (low). After getting it home and moving it around a few times I noticed it would not shift out of low gear. I checked trans oil and found it to be the wrong type it felt heavy like gear box oil (hypoid). If I drain pan of all the oil and add the correct type of tranny oil, will this alleviate the problem I have? Please help or give me some prudent suggestions that will help immediately.

RE: Stuck in low Gear
You may get lucky and you may not. There's a major difference in those two types of oil and if mixed there can be long term damage even if it seems better at first.

BTW, draining the pan and refilling with the proper oil does not get all of it out as at least half of the oil stayes in the torque converter. You may get better results with a trany "flush" (available at many shops) but that's not cheap and you still need to get lucky.

RE: Stuck in low Gear
Oh, forgot to mention there are a couple of "overhaul in a can" type additives out there that are VERY thick, almost like the old STP for motor oil. That may be exactly what's in the trany and it only covered up an existing problem till just now.

Hint: 90 wt gear oil has a distinctive smell totally different from ATF and most additives. If in doubt put some on a paper towel and ask any mechanic to take a sniff. They will tell you right away if someone put gear oil in there.

Also forgot to mention that this trany still has a govenor so if you have reverse and first it may not be a total loss. IOW, the gov may be bad or the gear that drives the gov may be bad so there's no up-shift. If you take the pan down and see small pieces of plastic in the bottom that would be the gear. OTOH, if you see lots of clutch material she's toasted.

Keep us posted on what you find.
