93 chevy 1500 4x4.. 4L60e trans Sign In

Hey guys as you know I have a 1993 chevy 1500 4x4... Anyway the trans has been rebuilt and its been fine.. However a few months back I had a trans leak.. So while I had it in the shop I had the guy to tighten the fittings down.. Well I didnt ask him to ck the fluid.. Well I checked it tonight while the truck was warm and hot and the stick has pinkish fluid on it but its in the cold part of the stick. So my question is
1) Do you think my transmission is okay it shifts fine a little rough but has always been that way even after the rebuild..
2) How much fluid should I add? And what typ of trans fluid its a 4l60e I believe.. I am really hoping that I havent messed anything up your input would be great again thanks..




If you cant fix it then dont mess with it...

Doesn't matter too much which transmission. Check level if in range to drive get it warmed up, level ground and check idling in park. Remember the increments are pints, not quarts.

Side note: Overtightened pan gaskets can cause that to leak! Need to be just right. Also (don't quote me) I think the "60" trans has 16 pan bolts and the "80" has 17 and usually a drain plug and tapered corners, the other more of a plain square pan,

Tom it wasnt the pan leaking.. It was one of the couplings in the trans line and at the top a bigger nut was leaking.. I just figured it was from the rebuild and I know how things kind of set in and you have a few issues.. The dip stick dosent smell burnt and the fluid is pink.. I will run to the store get me some trans fluid and add it slowly.. Not sure if it will read immediately or if it has to run throw the trans to be able to tell its at the correct level.... I think I am okay.. I had just read that if a 4l60e was a 1/4 low then it was probably damaged.. I hope not..

">>I had just read that if a 4l60e was a 1/4 low then it was probably damaged.. I hope not..<<"

Does that mean 1 quarter of total capacity low, one quart low, or a quarter lower than some marker on the dipstick?

No matter - a trans can handle SOME varience as it expands and contracts with tempertures anyway - the reason they say to check when hot.

When you've just added some it can take a while to get a good reading from the dipstick mostly because the tube going down is covered in ATF. If VERY low as if you had dropped your own trans pan and there ar known quarts now needed you would put that much back before starting up, shift thru gears, wait a minute and check to get into safe zone.

At any rate, trans shouldn't be consuming fluid. A coupler with a problem that you caught may be fine now that it's fixed.

The question of whether ONE quart low will or could damage a transmission is hard to say. I doubt it but I wouldn't be out trailer towing or continue driving if it was acting up at all,

Tom it isnt acting up.. I was just checking the fluids nothing else for me to do yesterday I got bored... Also when I do tow a trailor I cut off Over Drive I was told by someone here to do that because those trans heat up fast.. Which before my OD kept going out even after the rebuild.. Since its been fixed I just tow with OD off hope I am making since..Thanks Tom

Note on trailer towing: If you tow a lot an additional trans fluid cooler is a great idea and change intervals should be increased. The truck may say if it was built with the "towing package" which would be nice now. High heat is a real trans killer,

I dont think it has a towing package but I am not sure.. I have a small trailor 5x8 that I haul a riding mower on and a push mower with a weed eater and my gas... Thats only once or twice a week... I cant remember who told me here when towing cut the overdrive off due to how quickly they heat up... When trans was rebuilt the guy who is well known told me for no more than I am towing I didnt need the cooler... I will never tow more than what I have now if I do I will get that cooler added..So I guess the question is to leave OD on or do like I have been doing? Guess I am worried OD will go out again if I leave it on while towing...
By the way it only took a little fluid to fill it up and it still shifts the same and the stick dosent smell burnt so I am thankful for that...

By description that's a light load trailer IMO. Bet it's all lower speeds and not long distance. Overdrive might be told to cut out by temp but I never heard that one before?? It will if load on engine is more if engaged no different than passing a car when it's engaged, load it up and OD cuts out to allow more power or even the next lower gear speed dependant also.

I swear automatics dislike abuse of the way you drive as much as way too much heat. Bet you can't drive like a nut with the landscape equipment in tow!

Check out one next time your in some parts store. Some just go in line with the ones that are frequently already in the end tank of radiator and put a smaller heater core looking thing up front of even the condenser (if it has A/C) so it get first crack at cooler air.

Not towing myself anymore but did once - a lot and paid for it for not adding extra cooling. My own damn fault - heavy trailer and long distances in Summer heat.

You should be fine,
