No reverse There is no reverse. Just bought the truck so unaware of the history. You can put it into reverse, but it will not respond. It is very quiet, so no funny noises when changing gears.

For every car and truck ever made in the history of motor vehicles??

The reverse of how it was removed.

Google

year make model remove door panel

and work backwards.

All question need 'year make model'.

Hello Mike,
I believe... the big danger with hooking up batteries in reverse polarity... is the explosive RISK.

It seems you got away with that...

(although it is a VERY good idea to have fresh water & baking soda IMMEDIATELY NEARBY if you do manage to provoke an explosion. Once you are blinded, perforated by battery shrapnel, burned & soaked in ACID you won't be thinking clearly).

Most everything in your car is rated for 12 volts... the POLARITY is only important for magnetic direction... Such as windows going up instead of down... seats going forward when switched to go back... Lights don't care... Diodes and transistors simply won't respond...

With the possible exception of some rather unique POLAR capacitors ... but we know that is really not all that wise... No/yes?


Perhaps now would be time to analyze what the ORIGINAL problem was when the battery got removed, reversed... Make, year, Model... and operational issues... and history...

Just put the battery in correctly (Battery & Ground) ... and start with the BASICS.

FUEL, FIRE & AIR... I would be happy to make more relevant suggestions as you progress... Just comment me back.

Stay safe... work safer...!!

Is that a used unit?

If so-- then that is some elses junk

That valve body is dirty
Solenoids dirty

Can't be rebuilt or a decent unit,
with those problems

I think you will start your new relationship with the
S10, by doing a complete trans rebuild

See if the seller will share some history on veh

The transmission was slipping for some period of time
You were unaware of it

Now that you changed the fluid,the new
fluid only made it slip worse

I only tell you this, because I once owned a
trans repair business

You didn't do anything wrong,you just didn't
know you has issues

The trans will have to come out and be
completely rebuilt

Stop driving it, period

That is one vehicle you want to correct
right away

Remove the trans pan and replace the
Solenoid Control Pressure Pack
It is one part with all the solenoids in it,
and a common failure
It is about $332.00 wholesale
If you buy from a dealer or don't install
yourself, it will be pricy.

you need to replace or rebuild your transmission. i wish i had better news.

With high mileage automatic transmissions, that have not been regularly replacing the transmission oil, it can cause major problems if you do change the oil. The sealing integrity in the valve block can be lost by flushing with new oil,
Firstly, just check and make sure the oil level is correct. Do this by running the engine, with your foot on the brake, go through all the shift positions 2-3 times, holding in those positions for a few seconds each time. Then put into park , still with the engine running, and check the oil level . if its a little low, add a small amount at a time till you get the correct level, each time going through the shift positions and then checking.

Investigate the propellor shaft 'rubber donut'. It bolts onto your gearbox and the prop shaft connects to this.(uk terminology, sorry)
