new to this whole chat thing but here it goes. i have a 94 grand cherokee 4.0L I6. my dad bought it brand new, it is now mine with a little over 300 000 km. have done lots of work to it and not ready to let it go. tranny makes loud winning sound when in reverse or drive, 1st, 2nd. it also takes about a minute to fully engage.

once up to about 35 km/h, it tries to go to 2nd but seems to slip into neutral. then, what seems to work anyway, i have to park it, turn it off, start it, then try to drive until the problem repeats(and it does at 35 km/h), and do it all over again.

always well maintained. has tranny fluid. has turned brown a bit. i use Lucas oil additive in tranny, engine, dif.'s, specific to the part. am also good with doing my own work. what can i do? would like to do the necessary work myself, any special tools needed for a tranny?

my "moto" is if its broken, try to fix it, you can't really do anymore damage if you're smart about it. good way to learn. my e-mail is:

Welcome to AF!!

Too bad you are starting off with such a bad problem.

It sounds like things are past an easy fix here. With the ATF color change, clutch plate damage and seal hardening/shrinking has likely already happened.

Additives are never a good idea (IMHO)........... unless you have a specific problem and nothing left to loose or you use it, see if it helps in the short term, drain it and get on with the real fix if you need to.

Auto tranny's are hard to predict in how they will react to additives. Each manufacturer uses materials that require specific things of the oil and when you do the "backyard chemist thing" there is a good chance you mess up the original features of the oil/clutch plate friction in a bad way.

To do the work on the tranny you will need special tools and a transmission manual for your specific model. The manual will tell you what special tools you need. Some one with experience would be able to use some tool substitutions but if you don't have the tools or the experience to sub the tools it might be better to leave it to a pro. Then you get warrenty too!!!!:smile:
