Ok so my truck is in the shop for its transmission. my dad gives me a call a coupel days ago saying that the tranny guy said i got water in my tranny and i have to get it replaced, so i understand that. But then my dad said that water got in the radiator or something like that causing water to get into my engine? if there was a hole in my radiator i would be overheating and what not? im confused, not close to my truck, and depending on some dude 100mi away to do a good job without ripping us off.

 

The radiator has a cooler for the transmission inside of it. The cooler could have a leak and water could get into your transmission that way. If you get a new transmission you should either replace the radiator or disconnect the cooler in the radiator and install an aftermarket transmission cooler. I'm not sure I understand the question concerning water in the engine.

seeing as there is already coolant running through the radiator, I don't think water IN the radiator is the problem. In fact with the little I know about engines, I am pretty sure the only way water is getting into the block would be the intake or oil somehow. depending on the "solution' this mechanic has for you, I would say it was either relayed wrong to you, or someone is bullsh!tting you about problems.

 

well i think i got it. i didnt kno the tranny cooler was in the radiator. ill ask and talk to the guy myself to find out what really is going on. thanks guys

 

The tranny lines go inside the radiator, there IS a serperate oil cooler for the tranny, but lines do go through the radiator.

It is so that your transmission gets to op temperature faster...go figure

I had the same problem as you, I got water all int he lines, they just flush it, it's not bad.

The only way to get water in your block would be if you have a bad head gasket or cracked head, but even then, your motor probably would not run right. I can almost assure you, you have NO water in your oil/motor.

As far as the tranny, buy one off ebay for 800, give them 200 to install it, it's a lot cheaper than a rebuilt for $2k!!!

 

If the transmission heat exchanger inside the radiator leaked coolant into the transmission, then you can bet that there is transmission fluid in the coolant system of the engine, too. You'll probably see a pink frothy liquid in both.

I just went through this with mine and it has taken a new radiator and a great deal of effort to get both systems back to normal. Luckily, it wasn't driven that way, so there was no need to replace/rebuild the transmission.
