Take a look at your linkage first...it may have been bent while off-roading.

Yes you can take it off.

The main problem - stuck in low gear indicates that the shift solenoid may have gone out. In that case it must be replaced. This happens to all these vans eventually. BUT, you might try checking the transmission fluid level just to make sure it is not too low.

need trans hi gear cluthes are probably bad. total rebuilt is needed if done diy flush lined and install extra cooler for trans

My experience would say that your 1st gear in your transmission is shot,

this happens if the crank pulley is not torque to spec this can only be done with special tools

check your tranny oil. should be pink. might just be low on fluid.

There should be a bolt and clamp holding the spedo gear housing in to the trans. If you find out there is no problem with gear. If your cable was broken and you replaced with universal cable make sure that it is long enough to be engaging into the spedo and the gear. I guess if all of that fails it would just about have to be the spedo itself. Good Luck

due to icy temperature the your brake fluid froze i suggest that you might flash the brake fluid..every 2 yrs the two thumbs up to flash your brake fluid because when it get old due the boiling point went low that can cause or losing brake in high or low temp..let me know what happen after flashing your old brake fluid
