New Modified Transmission Flush Method with Pictures

Check out this Modified Transmission Flush Method

The tools required are few: Along neck funnel to access and reach the dipstick and transmission filler tube, a 15/16 or 24mm box/open end (not a 1/2″ drive ratchet since it will not fit between the drain plug and the rear brake fluid lines), 5-6 feet of 1/2″ I.D. clear tubing (5/8″ID will be too wide), snap-ring pliers, and a 6″ electric zip or cable tie for added security after replacing the transmission line clip when you are finished. In addition, a new crush washer for the ATF drain plug (same size as the oil drain plug) and a drain pan will be needed.

Did this on a C70 2004. I was experiencing hard shifts and slipping. Did it with a case of Toyota fluid IV. Works like a charm. I was told by the volvo dealer to get a new gear box!

Pretty easy and effective transmission flush proceedure that fixed my 2002 V70 auto trans shift problems.
1. Drain trans from plug into pan (appox 3 quarts)
2. Refill with 3 qts Mobil 3309 Trans fluid.
3. Drive 5 mile route filled with stop signs to exercise/flush all pistons and clutch packs (clutch packs and pistons fill and drain through a single port, don’t flush)
4. Repeat three times.

HI All,
2 mechanics said MY 1995 850 tranny was shot. Volvo repair shops said its too bad< i need to drive it till it dies and pon up for a used tranny. Car would shudder and not go into 1st gear without the shudder. Hard time shifting from 3rd to 2nd also. Would put tranny into neutral coming to a stop sign and while waiting to go, made terrible noises.

Did the flush as recommended here, except used std DEx 3 fluid.
Flushed between 19 and 20 quarts.

Transmission is working as well as it has since I bought it at 125 K. THANKS to all of you so much.
Blessings
Jack
