Blown 346 Posted March 11, 2014 Report Share Posted March 11, 2014 If its just a leak more than likely its the seal. No need to take apart the trans. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted March 11, 2014 Report Share Posted March 11, 2014 If its just a leak more than likely its the seal. No need to take apart the trans. Which seal would that be? There's more than one.... There are a multitude of leaks that can occur, I believe my truck has had them all. Where is the drip coming from?

Blown 346 Posted March 11, 2014 Report Share Posted March 11, 2014 leaks can vary from vehicle to vehicle. The most common are from the trans pan, tail shaft, torque converter seal and or hard lines. My point in case you missed it was just because its leaking doesnt mean you have to dis assemble the trans and rebuild it. Quote Link to comment Share on other sites More sharing options...

Fireman31 Posted March 11, 2014 Report Share Posted March 11, 2014 Time to head to a transmission shop, a leak from that area could be a failing torque converter, or leaking front pump/pump seal. A good trans shop should be able to pinpoint the source.... Quote Link to comment Share on other sites More sharing options...
shawnss Posted March 11, 2014 Report Share Posted March 11, 2014 So did you say its now slipping? Was the leak bad enough where you ran it low on transmission fluid? Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted March 12, 2014 Report Share Posted March 12, 2014 You have to remember though just cause the trans slips doesnt mean it needs to be replaced. Like said above, it can be low on fluid. Find the seal or issue why its leaking and fix it. You could be wasting money on rebuilding for just a seal leak... Where your leaking from is a normal seal issue with these tranmsission from the silverados, Tahoe, TBSS etc. its considered normal wear. If it leaks when shut off, its either a gasket or seal, this is called a gravity leak as the trans fluid drains back down from the trans and converter. If it leaks while running thats a pressure leak. Quote Link to comment Share on other sites More sharing options...
