A4LD reverse problem
1985 Ranger 4X4 with A4LD transmission , 2.8 V6 engine & manual lever in floor for 4X4 & Hi & Low range . Transmission seems to shift & hold properly in forward gears . With transfer case in Hi range & the truck on the level or a very slight incline reverse works as long as you are easy on the gas . If on a steeper incline or if you goose the engine reverse lets go & just slips .
With the transfer case in Low range the truck will back up steep inclines & will spin the tires without slipping . I would think if it has a pressure problem or worn clutches or bands causing the problem that it would also slip in Low range before spinning the tires . Fluid has been changed & is at proper level on the dipstick . What do you think ? TIA
ETA- Have also adjusted bands & torqued valve body to specs.

Well, for starters, low fluid levels can cause engagement problems, so check the fluid level. Old fluid can cause problems too, the fluid in an A4LD should be replaced every 30,000 miles. Lastly, just wear and tear can first show as engagement problems.
Since it seems you have already changed the fluid and it is at the proper level, I would say that wear is starting to take its toll. Adjusting already worn bands does not always have the right effect. Your valve body could also have internal problems that prevent a solid engagement.
Things are always less likely to slip in low range, and any slippage would be less noticeable.
