JB weld?

 

[slackjawsk5]

not the jb weld....the round plug looking thing

speedo hole for a 2x4 version of that tranny. just a freeze plug .

 

[slackjawsk5]

how is the plug installled? and if thats where im leaking tranny fluid what kind of performance problems would that give me and is that plug easily fixed?

 

[sweetk30]

just pop it out and replace it. it is just a dummy plug to block off the spot. performance is lost when fluid is low and tranny slips.

take punch and spin it in the case . then grab it with plyers and pull out. then clean up area good. get new plug and aply some permatex tach and seal to the sides . ( red thin super sticky stiff in white bottle. ) then use big socket that just fits in plug center and tap it in with a hammer using the socket as a driver.

hey thanks sweet

i ll try that. would that affect anything else by leaking like vaccums

 

[sweetk30]

na just fluid sits in that area.

 

[slackjawsk5]

you dont think its possibly cracked in that area do you . i was looking around at some other posts and someone was saying that the np203 is heavy and if it was offroaded hard it could of cracked. so the guy before me could of threw some jb weld on the crack and let it be

hopefully just the plug though

 

[sweetk30]

best clean it all off with brake cleaner and scrape off the other crap and check over for leaks. if cracked remove tranny drain it clean it good and have it tig welded by a good welder that knows aluminum if its a simple crack. if real bad find a new case.

 

[slackjawsk5]

thanks again sweet

 

[sweetk30]

also just incase you dont know thats a th400 tranny.

 

[slackjawsk5]

yup knew that already just a little confused about the jb weld

 

[sweetk30]

p.s. little note . welders HATE JB WELD PAIN IN THE ARS TO WELD ON. so if need to weld it remove all of it and thay will thank you for it.

 

[slackjawsk5]

cool ill start on that tomorrow
