transmission flaring between gears

W140Gill, first let me say thanks for your post I just replaced numerous burned out lights because of your post. But my transmission is acting really weird lately.
When I begin underway it revs to 4500 rpm before the gear will change. Then if i give it gas at the wrong time it will rev really high! The gears just aren't changing right. Is this the transmission flaring you spoke of? How much did it cost to fix?

transmission flaring

Ok w140Gill, I will be cautious. One question was your car driveable, or did it completely break down? Mine drives now and I was just wondering. If yours drove how long did you wait before taking it in to get fixed?

I will do it as soon as possible

Thanks w140Gill, I get it looked and fixed as soon as my pocket allows. I just wanted to make sure driving it like this for a couple wouldn't destroy the drive shaft or something.

ac/ heating controls illumination

w140 Gill, have you changed the bulbs in your ac/ heating ever?

I have a blown one on the drivers side of my control unit. If you have any instructions could you share them with me please.

Thanks in advance,

Dear Ychachad, thanks for your post I saw that from our buddy Gill. But I was trying to remove the bulbs from my air and heat controls. The bulb on the drivers portion is out, so I can't see what temperature it's on at night. I changed my gear bulb thanks to Gill, so I know how to remove the ash tray and those parts. I was thinking the top portion of wood must come off in the same fashion exposing the air and heat controls. I also need to replace whatever bulbs light the vent on and off controls If you have any knowledge on these let me know ok.

Wiring harness

Hi Gill, as usual I have a question. What were the symptoms when your wiring harness went bad. Lately in my car when I'm driving all the warning lamps will flash as if the car is gonna shut off but I feel no affects to the engine. Is this my harness? I have 153,000 miles on my car.

As usual Thanks for the info Gill
