View Full Version : I have a 91 Toyota Previa Van and if it hasn't warmed up it will not shift into 4th

gear and also...? It will also make a funny smell. What is the best way to prolong a transmission. Will using the Drive and Overdrive switch prolong its life?. What do you feel is the best additive to transmission fluid?

You need to replace the transmission fluid.
Use 14mm socket to remove transmission pan under the van
It is right at the middle of the van, close to the sliding door.
You need to remove all screws and remove it. drain all fluid.
Go to Toyota dealer to get transmission fluid.
after cleanning the pan, replace it back.
replace it with clean fluid, it is right under the drivers seat.
Hope that will help

For future reference, this is normal. Once the motor is warmed up, overdrive will be available...

you dont need to buy expensive dealer transmission fluid for that vehicle autoparts store is fine. You can add a bottle of LUCAS trnny treatment when replacing dont pass the cold mark on the dip stick,do it when cold,the fluid is considered cold after 4 hours. to prolong the tranny life u can add an external tranny cooler, check AUTOZONE or UHALL. I use it along with the radiator some people elimnate it because it is hot . heat kills tranny and snow without traction .

Make sure that you haven't bumped the button on your over-drive that is on the tip of the shifting lever.
