Question about Cars & Trucks

1 Answer

What kind of transmission fluid do I use in a 1985 Southwind by Fleetwood RV. It's built with a GMC 3500 engine. I bought it used so have none of the manuals, etc.

I bought the RV well used. Runs great, but don't know what kind of transmission fluid to use.

Any garage or mechanic would tell you this as they have manuals to show them this information.

SOURCE: What kind of fluid do

If the vehicle has an Automatic Transmission: Dextron II

If the vehicle has a Manual Trans, its complicated.
Depending on Trans model:
The 77mm 5-speed and 89mm 4-speed overdrive use Dextron II ATF.
The 117mm 4-speed uses API GL5 SAE 80W90 gear lubricant.
GM recommends Synchromesh Trans Fluid (1052931) in both the 85mm 4-speed and 5-speed.
Hope this helps!

SOURCE: I have a 2000 Ford

there are two transmission cooling lines that go to the radiator. If you have a six cylinder it is possible that one of the lines has a hole that is spraying on to the exhaust. this would account for no leaks on the ground. When you start the car it will start to spray right away. These are metal and rubber hose lines, so if and when you find a leak it can be cut out and replaced with hose and clamps or you can get the original hose and replace all of it. Not hard to o . Let me know. Randy

How to check check engine light on1994 fleetwood southwind rv with scanner

It should be on the left side of the steering column just after it enters the dash. It may be bundled in with all the other wires in the harness making it hard to see. It also may have a dust cover on it. If you are looking for the connector to be mounted on a bracket this may be the problem. Don't look for a bracket, look for a loose connector.

My 85 monte carlo ss does not go into drive until bout 3500 rpm why is that

If your automatic transmission fluid level is correct (check it first) ie.:with engine running, in park, engine at normal operating temprature, check dipstick. If OK: then it might be a dirty (clogged) transmission filter. Service the transmission, replace the filter and fluid.

How to replace filter (diagram maybe?) in 400 turbo automatic transmission thats sitting in a 1985 fleetwood southwind motorhome?

  1. Check the fluid level. The first thing to check if you suspect that the transmission is acting up is the automatic transmission fluid (ATF) level in the transmission itself. The dipstick on the TH400 can be found inside the engine bay, on the passenger side toward the firewall (opposite the radiator). Pull the handle attached to the dipstick, which will remove it from the dipstick tube. Clean any fluid off and put it back into place, making sure that it seats all the way. Then remove it again and look at the tip of the stick. There are level indicators there, which will tell you if the transmission is low on ATF.

  2. 2

    Check the linkages. The linkages that are connected to the shift lever can get out of alignment at times, causing sloppy or difficult shifter response. Look for abnormalities such as bent or broken parts, loose attachment points, or blockages that would prevent smooth shifting.

  3. 3

    Change the filter. Unbolt all 13 transmission pan bolts (on the bottom of the TH400) and remove the pan. The filter is found in this area of the transmission. Filter kits, which include the filter and a new pan gasket, can be found at any auto parts store. Replace the filter and fill the transmission with new ATF (the TH400 requires six quarts). Do not put the bolts back on too tightly, as the gasket can become damaged. Six to 8 foot-pounds should be plenty. If no torque-wrench is available, just put them on as tight as you can by hand, and then turn them 1/2 revolution.

  4. 4

    Inspect the cooler lines. The number-one killer of automatic transmissions is heat. If the cooler lines that come from the radiator are damaged or leaking, it might be necessary to replace them. These items can also be found at the local parts store.

Fluid type in 1985 gmc sierra k2500 4x4 aluminum transfer case

You can use the same ATF as the transmission or a synthetic ATF for GM Transmission. Most guys will use normal ATF and mix Lucas ATF transmission additive to it, to make the fluid last longer. Good luck and hope this helps. There was two types of transfer case available to your truck. NP205 takes 5.1 pints NP208 takes 10.0 pints
