Thread: transmission dust cover size

Tweet

Can someone tell me if a th400 and th350 flywheel dust cover are interchangeable and if there are any variations based on what size flywheel you are using?

I want to scrounge one from a salvage yard but dont want to pull something that dont fit. Thanks all.

i dont know for sure, but i think they are the same. the junk yard will know.

Thanks Lt1. Based on past experience, they are not reliable. Anyone know for sure on differences ? I'd only like to crawl in the dirt one time if possible.

Don't know for sure but the one Mr. Gasket sells (chrome) has the same part number for 350/400 ..........

Jegs part no 720-5115 for $36 ...........

(I bought one recently)

been there done that, dont know why, couldn't see it.

Well, my experience conflicts with what has been indicated so far. I had one of those cheap chrome stamped steel covers on my TH400 and was looking to upgrade to a nice thick polished aluminum cover. The only one I could find at the time, about a year ago, was one for a TH350, well the salesman said "no problem, it will fit a 400".....wrong! The covers were the same size alright but I had to drill and tap new hole in the upr R/H corner of the trans and enlarge the slot on the cover for the upr L/H hole. Now, it would have been easy for the manufacturer to make this cover to fit both trannys but such was not the case and I ended up modifying both the cover and the trans to make it fit. Anyway, thats been my experience. By the way, that's a heck of a good price on those E-bay aluminum covers, I think I paid close to $80.00.

You mean like these
