DIY Racing Turbo 400 Tech Tips (part 2)

[@gregh6794]

Good job. Excellent you mentioned the rear bush. Repaired that exact problem some years ago. Bush hadn’t spun just moved.

I wouldn't be too hard on yourself about leaving that stuff out. Thanks to your first video that I compulsively watched over and over I went from knowing zero about transmissions to building a th400 and 4l80e for my own projects! The only other info I sourced was paying attention to Hutch on the Chevelle forum (I think) and piecing information together from crankshaft coalition's th400 wiki..

Hutch is a very smart guy. And congrats on your builds ,, Tobby.

@@tobbystransmissions6046 thank you sir, that was a very kind comment!

Glad I saw this before assembling mine thanks for the info on that position adjuster and the tail bushing

Putting one together again for the drag car. I hope I got it right this time!!!

Good morning Mr Tobby. Thanks for taking the time to make these informative videos. I see that you're pretty well stocked up on TransGo shift/Reprogramming kits. Can you tell us which TransGo kit you prefer for your high HP/drag racing transmissions?

[@peterzetterberg9665]

interesting about the oiling on tailhousing

I'm doing the sonnax th400 case saver and using a full manual valve body that keeps the band. Can you upgrade to the wider 1.25" front band while using the th400/early 4l80e case saver? Will it need the later longer servo pin if it will work with the wider band? I know you can use the wider 4l80e band with the longer servo pin in a 400, but will it still work using the sonnax case saver/intermediate snap ring support?

Yes

I do have a question so I Polarized the back end with the 350 pump bearing and shim I got close to the factor shims but is there a actual end play specification. I have .014 with the center support in

Will a 4l80e wide front band work in a th400 or is it even needed?

[@funfun8095]

Yes. No, not "needed".
