Neutral Saftey Switch Replacement

Hey guys!
I was changed my neutral safety switch on my 89 islander with a 4.2l on the automatic transmission and a whole bunch of fluids came out pink and red. Is that supposed to happen and if so what should I do about it?
Thank you

Does your transmission have a dipstick? Simply follow the instructions in your owners manual for how to check automatic transmission fluid level and top it off if it's low.

In my minds eye, I can't see how two different colored fluids came out of the same opening. Was the pink fluid milky? Was the red fluid transparent? Did you take any pics?

I assume you changed your neutral safety switch because of starting issues. Did it fix the problem?

Good Luck, L.M.

My transmission does have a dipstick and it's very low so I know I need to refill the transmission fluid. I don't have any pictures of the fluid but the majority of the large amount of fluid was milky pink and red. I was just wondering if it was normal for tons of fluid to come out of it. I attached some pictures and I'm still waiting for the part to come in.

The Factory Service Manual states that the transmission fluid should be dark red in color.
If the fluid is discolored but the trans works well, change the fluid and filter.

The milky pink fluid you saw was probably a result of the transmission pump mixing air and trans fluid because your fluid was low, allowing air into the pump. The normal pink fluid was probably trans fluid that the air bubbles had settled out of.

If you haven't changed your trans fluid in the past 30K miles, or if the Jeep is new to you I strongly suggest that you change your transmission fluid and filter.

Good Luck, L.M.

Hey so I changed my neutral safety switch and my reverse lights are still not working and my transmission is leaking. I took it to two different shops and they both said that the leak was from the neutral safety switch and not the transmission pan gasket. How is that possible?

Procure a Factory Service Manual.

The FSM describes how to diagnose the reverse circuit. How sure are you that the Neutral Safety Switch is the culprit? Have you checked the bulbs? Have you checked the wires?

When you installed the new switch, did you replace the seal? A new seal should have come with the switch.

Good Luck, L.M.
