Sometimes after the car is warmed up, it won't shift into Reverse unless I rev it a little.

I have flushed the tranny fluid on my '93 940 turbo, added some TransX with the new fluid, redid the bushings on the shifter arm, adjusted the shifter so it has equal travel front and back, and checked the AT fluid level to make sure it's perfect...

So what's wrong?

As I said on an earlier post about this problem, the car only has 98,000 miles on it, and I'm having a hard time believing the tranny is already dead.

Should I pull the pan and clean the filter?

Is there a way to re-adjust the shifter to make sure it is solidly and firmly in reverse gear?

Hello, Your getting there. Your valve body seems to have a jam in the reverse valve. Keep on reving with the treatment in there and give it another week. Valve bodys aren't that hard to change, so give it some more time. To make sure your in reverse, remove shift rod and engage reverse from transmission. Work the shifter until your in reverse and the back-up lights are on. Now check to see if the rod fits between the two bushings, if its a little short lengthen, if long, shorten. Pauli

Thanks Pauli,
So you think pulling the pan and cleaning the filter is not necessary?
And I know almost nothing about transmissions... what and where is the valve body?
Also, replacement of the rear bushing keeps being suggested. When I pulled the shifter bushings, they seemed perfect, but when I look in the 700/900 FAQs, this reverse problem is listed as a symptom of faulty bushings...

Hello, It couldn't hurt. The screen inside the pan can be cleaned with brake clean. I didn't think your shifter bushings were gone, but if the adjustment is off a bit it can effect engagement. Valve body replacement is best left to a tranny shop or a qualified mechanic. There are three pistons that will fall out when you remove the valve body and the TV cable can be a bit difficult to install. I think a good slippery additive might help as well. I haven't had much luck with Auto R X treatment in a tranny, but anything that will get rid of the gunk that is binding your reverse valve will help. Pauli

Did you see this post in the FAQ?

Thanks for the reminder.
I had seen that FAQs, but I had forgotten about it.

Have you, or anybody else, replaced the rear tranny bushing?
Is it obvious when they go bad? or is it more subtle - less flex and more brittle?
