After Driving for Awhile, In "D", tranny Slips into Neutral Under Load..

[brentwoodboy]

I posted before about my Manual Lever Position or Neutral Safety Switch, but if I drive for 20 mins, and from a stop, if I floor it in "D", it disengages into neutral and doesn't engage again until the RPMS drop down...anyone know what my problem is?

are you sure it's kicking out of gear? Could it be slipping? When it engages back, does it shift hard or soft? You have a shift kit so it should jump if your rpms are above idle.

Might check your shifter cable and make sure it's adjusted right. If you are off a 1/4 inch it could be inbetween gears.

Well see, the thing is, it will only do it if its been running a while, like only if the tranny is hot. If I put her in "1" when its hot, it won't slip into neutral, it has to be in "D" to slip. When it does slip, it shifts back hard. Tranny was rebuilt about 1 1/2 years ago,.,,

I would check the cable. It's a free and quick check.

Oh and check all your plugs.... and your harness. Mine came off the firewall and burned up on the exhaust. I started poppin fuses in the O/D shut off....

Umm, stupid question...is the cable under the car or do I get to it from on top, thanks for your help.

Have you checked the condition of the fluid? Does it smell burnt? You also might want to look into a auxillary transmission cooler. It's cheap insurance for $50.

Have not checked the fluid lately, might wanna do that. I have looked at tranny coolers but havent been serious about purchasing one. I'll do that some more.
