ok guys im having a hell of a time just getting this car on the road what had happened was i went to mvd to get it licenced and regestured in the morning when i got to my house to start it and take it to work and show it off so anyway put it into reverse and backed out of the shop went to put it into drive and nothing tryed all my gears just had reverse guys im stumped at this point my fluid is brown but doesnt smell burnt trans linkages is fine i havent pulled the pan yet
here in the usa a rebuild kit for the trans is like $400 and torque converter is 300 or so i dont have a problem rebuilding the trans my self but what is my best bet to look at and what would you guys do
im getting to know this car inside and out let me tell you i think i got volvo fever
oh by the way sorry im not familiar with auto trans like i am with manuel trans because i deal with them on a day to day basis
thanks guys for all you help

hi there not sure as only ever seen one d24 with auto box could it be a cable thats not right or is it straight select from the gear lever it seems funny that you have reverse but no foward

its a straight lever from the shifter to the slushbox (auto trans)

The green book advises fo this problem: Check 1. Oil level 2. Kickdown cable 3. Shift linkage 4. Line pressure and stall speed 6. One-way clutches 7. Overhaul transmission.
If you want any part of the book mailed to you just ask. The problem in doing these things is knowing which of the list is the most likely culprit. Plus several special tools are said to be needed and without experience one wouldn't know which of them were essential.

Mister T probably knows a thing or two about automatic transmissions. And he is 'only' 450 miles away..

What tends to happen is the shade-tree mechanic trick of revving it well beyond idle revs in Park! If this is what happened then they owe you a new ZF4HP22 gearbox. Volvo issued a service instruction many years ago for any car with the ZF box, forbidding use of revs while in Park. The internal pump is not connected in Park. When they take no notice of the instruction they find themselves paying for ALL remedial work needed (new/refurbished gearbox, oil and labour costs). The ZF box is also fitted to Gasoline 740 GLE (non-turbo) models.

All the best, Peter.

im no shade tree mechanic im a professional diesel mechanic
yes i found that out when it was to late i didnt know that those trans did that **** form what i read that an aw 70 or 71 is a better transmission what years of car would that trans be in

It is possible that the forward gear is not being selected due to linkage problems. There is absolutely nothing wrong with the ZF box. It was due to "shade-tree mechanics" not grasping that, there is no need for the pump when the box is not working, ie in Park. This is what you get when you use superior German technology in a superior German gearbox. The AW 70/71 boxes are not so strong and a bit more "agricultural" in comparison. They are also basic three-speed models wioth an overdrive unit tacked onto the back. The ZF is a genuine four-speed box with a lock-up facility on the torque converter, which is why the AW box with suffix L is better than the standard AW box. It turns the ZF into a five -speed box as it automatically engages over 56-59mph. I have had Lancia with 3-speed ZF box which towed a caravan with no problems and that box also had no pump connected when in Park.

I certainly did not mean you to think that I rated you as a shade-tree mechanic!! far from it, as I know of your big rig experience. I mentioned the trick to tell you how it came about. It actually made them give up working on Volvos till they had built up their experience.

All the best, Peter.
