Internal Transmission Leak - BMW Forum

cymorg · 07-30-2005, 09:15 PM

so my check engine light has been on for FOREVER and i got it checked out, went to the dealer and all

they said i had an internal leak and were also gonna replace some sort of pan under my car (cause they said it was banged up) but anyway--- they wanna do it for about $1700. that seemed a bit steep to me.

is this a repair that could be done elsewhere for much cheaper? ive been driving the car like this for quite a long time and havent noticed much difference. it seems smoother somehow when changing gears, however. before the problem i would feel sortof a jerk or something when it changed gears, but now u can hardly feel the gears changing at all. the gears *are* changing and its driving alright, im just worried. a lot. i dont want to buy a new transmission. oh yeah, i have an automatic transmission, 1996 318is.

has anyone on here had a similar problem?

THANKS in advance.

If it needs to be done, make sure you get a quote from the dealer. And when I say quote, I mean they should print you out a parts list with labor and such and with a grand total. You can probably find the parts a lot cheaper online and the labor can be cut in half or you could do it yourself.

a relative of mine is a pretty hardcore mechanic but he's never ever worked on a bmw that i know of

do u think it would be possible for him to fix it? i mean, how difficult of a fix is this?

Couldn't tell you really. If I knew what parts you need to replace it would be a lot easier. Find out what the dealer needs to replace to fix your car.

all they gave me when i talked to them was a paper from (i assume) the mechanics saying this:

"need to install THMR1 internal repair kit before further diagnosis of concern.

patwiper inserts
parts-$360.00-no
labor-12.6+ 1.0 diag"

can u tell from that? whats a thmr1 internal repair kit?

oh & also they have written on here that the TCC in the trans is leaking fluid pressure internally, that the pan is dented, and that the tcc module is shorted.

????????????????????????????????

The only thing I can hypothesize the 'TCC' being is the Torque Converter. Below you will see alink that shows all the parts and part numbers for the 318's auto trans. Do a little clicking and see what you find.

AND the link delow shows you ITEM NUMBER 3 Torque Converter Solenoid Valve... which may be your TCC Module...

I'll see what my Bentley Manual says

e36surge · 08-02-2005, 03:59 PM

TCC is the Torque Converter Clutch Solenoid Valve

cymorg · 08-02-2005, 08:25 PM

yeah i remember him saying tcc stood for torque converter clutch or something like that.

you guys are amazing.

so any idea what this $360 for parts could be? and if they only work 12.6 hours then thats me paying them $106/hr. to get up to the $1700 they estimated for me. jeez. i dont think my uncle or i can fix this on our own so I guess i'll just take it to someone (NOT the dealer) and see if they'll charge me less than $106 an hour to do it.

thanks for your help!
