Ok so I am new to the forum guys , but I have a 2001 blazer 4x4 , 220,000 miles. Just rebuilt the engine and after getting the engine back in discovered the dipstick on the tranny leaking pretty bad. Anyway after fumbling around with the rubber seal at the transmission part of the seal is now broke off and in tha pan. I have not run it like this and wasn't wanting to go into the tranny because of all the miles. I just want some advice on if I should leave it in there or go in and get it and replace the filter and whatever fluid I loose. I don't know the history with the truck so don't know if the transmission has been serviced as is should. But I don't like the thought of a 1/2" pc of rubber floating through it. I wouldn't think it would pass the filter but who knows. Any advice would be welcome ...

 

It won't hurt a thing to remove the pan and retrieve the seal. Fluid & filter should be changed every 36K miles. A transmission fluid flush is not a good idea regardless of miles. Use a torque wrench when reinstalling the pan bolts. Torque spec is 102 inch pounds, (NOT foot pounds).

 

Ok thank you I tend to agree with you . I have just heard some horror story's about trannys with high mileage and fluid change. I guess if it goes out It was due to be rebuilt also lol.

 

i`m with captain hook.It will never hurt a transmission if and when you change the filter and fluid.But never flush anything.When you flush something..What does it do?It creats small particle`s,which floats around and flows like water.The particles will tend to follow the least path of resistance.The filter catches some of these small particles.Not all of them.On most (4L60-E/700 R4`S) Transmissions, the filter connects to the pump.If the filter is clogged with small particles?It will damage the pump.But there are rumors with people who say"If it`s an old tranny with lots of miles on it?Don`t worry about changing the fluid and filter,because it wil screw the tranny up!"That`s not true.I always change my tranny fluid and filter once a year, no matter what.Plus having a tranny cooler too.Your transmission will last alot longer if you keep up with the maintenance, plus have a cooler on it.

 

I guess I know what I a doing this weekend . Thanks for your advice . I agree wth all you yes have said.

 

actually the problem with flushing a trans is not that its going to plug things up, what you end up doing is removing all the grit in the older fluid from wear on the clutches, older clutches need the grit in the fluid to help them grab and not slip. by changing fluid in the pan and filter it's adding fresh visscosity fluid while leaving some grit in there. The mith on changing fluid and burning up transmissions was started because by the time most people get around to thinking about changing fluid and filter is after trans is already slipping and the damage is done and it's on it's way out so they blame the fluid change
