Hello, i have à delta 88 Whit à th400 that spitts oil from filling tube, i have read about the same problem from other menbers but i couldnt find any real answer i know that the first tought is that the oil level is to high, but its not.
Hope to solve the problem so i can enjoy my car this summer and not be afraid to be stranded somewhere thanks alot and sorry for my bad spelling!!!!

Did you check the flid level with it warmed up and in park, with engine running? There is a vent tube on the case of the transmission, it may be clogged. Can also be a bad filter or the transmission is toast.

Yes i have check the fluid the right way and the vent tube is ok, probably the trans has to be rebuild, is there anything that the motor can couse whit the trans? Like vacum problem or something? I tried also to change the vacum modulator but it doesnt help, thanks!

I've heard of this problem before but I don't know what causes it. Have you checked your transmission cooler in your radiator? Maybe the transmission fluid is overheating and boiling...

Mine leaked after i put it in. Just need a new seal.



Wait are you talking about it going up the tube?

Mine spit about half a quart once and punched the dipstick up against the hood. The cause was a clogged vent tube. ran fine after I installed a complete new tube. make sure its clean at the trans as well as the opening.

rjohnson442

a vacuum problem would cause it not to shift, it's a pressure problem in the case if it spits all the way out the fill tube.

Torque convertor. My 2004r shot fluid out, but also acted like it was 5000 stall, major slippage.

Tranny lines coming out and going to the right
place on the radiator?
Top on tranny to top on radiator. Lower to lower.
You never know, I have seen them backward.

Cooling lines hooked up backwards will not cause this.

My chev van does this, whenever it sits without running for a few days.

I have narrowed it down to a 2 part problem...... the dipstick grommet doesn't have a perfect seal, so I run it a little low on fluid to prevent it from leaking while driving.


The reason it leaks after sitting for a few days, is that the fluid from the torque converter creeps back down into the pan, which allows the fluid level to rise....allowing the dipstick tube to leak once again.

I have also checked trans cooler and blew trough it, the vent tube seams to be ok becouse i have put some small string trough it, and i dont think its boiling becouse it spitts allmost right away when i start driving, i have been think about the converter but some told me it cant be the problem, but i dont know! Thanks,

marcoandersson

If the torque converter/turbine is broken what happen then.? And is there some way to check the tc if its damaged? Thanks

I hope it's not what I just encountered for the first time: holes in radiator, allowing water into trans cooler, filling up transmission.
