Re: 1999 Jeep Grand Cherokee after shifting out of 1 to...
I'm getting that you have a shift problem? Lucas is good stuff but if trans oil looks funky, change it and filter THEN an additive. You can only drain pan, so converter still has a lot of old fluid in it. If it starts getting any better after change, do it again in 2-3 weeks. Other than that, trans problems are usually internal and require teardown and rebuild.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

this may have been problem[low on fluid] may be time to change that trannny fluid and filter. if you choose to do this , i recommend that you add lucas tranny treatment to the fluid change also w/new tranny filter. this frees up any sticky valves in your tranny. allows smooth shifting, and works well wlth any fluid for fords/chevy's or jeeps. the lucas will eliminate the hard shifting, been there done that issue. also the hard down shifting you did'nt mention. although you may have not noticed. add the lucas and your hard shifting issues should be gone. thank you for choosing fixya.com
sounds like a possible shift solenoid. If it's due for a fluid change, do that and add a container of lucas trans conditioner. Likely you have a drain plug on the pan so if the fluid was recently serviced, just drain a quart out and replace with the additive, then top off. If the condition does not change within a week, likely you will need better diagnosis from a reputable trans shop.
check to see if your fluid is low or burnt. if it is low then just add enough to cover the fill mark on the dipstick. if it is burnt, remove the transmission pan and filter and replace the filter. then add new transmission fluid.
don't like putting chemicals into transmissions but you could try adding lucas conditioner. it takes time to form gummy deposits and may take time to free it up. Only other option is to have the valve body and possibly the governor cleaned. and any shift solenoids checked.
have the same problem with 1999 mazda pickup try flushing the tranny and put in a new filter replace one quart of tranny fluid with some lucas trans fix and see if this helps it any, was told the tranny will need to be rebuilt.
That's called flairing and is not a good thing (indicates pressure loss inside unit) If you haven't changed the fluid in a long time sometimes a fluid and filter change with an additive such as lucas conditioner may help. Generally though, there is no real chemical fix that replaces worn parts.Depending upon where and how worn your unit is, sometimes doing this will prolong use for many months. Or, it will have no effect at all. Sealing will not happen overnight it took a long time to get this way.If you need an immediate fix, have it rebuilt.
Likely it hasn't been serviced in a long time. I'd try changing the fluid and checking to see what's in the pan. If filter is plugged up and there is an extrodinary amount of metal or clutch material in there you may need to replace unit (some debris is normal). If fluid change helps, do it again in about 1500 miles. When you drop the pan, you have changed only about half of what's in there. A good additive may also help... I've used one made by Lucas from time to time and it has actually helped, when the unit was gummed jup but not internally worn out.Don't expect anything to remove problem overnight, it took a long time for varnish inside unit to get there!
