4R70W Reverse Gear Noise

[technoboy235]

I have a 1998 Explorer with a 5.0L engine and 4R70W transmission. When I put it into reverse, it makes a whining noise similar to the noise a locked transfer case makes in 4 low. When it started doing it, it would only make the noise until I gave it gas. Lately it hasn't been stopping when I rev it though. I don't know what the noise means. I hope it doesn't mean a new transmission but its worrying me.

Does anybody know what could be causing this?

Thanks :navajo:

I have decided to just drive it down to Florida and rebuild the transmission. It has about 200,000 miles on it anyway which means that ist only a matter of time anyway. If anybody still has some info or advice on the subject, by all means post it.
