Th400 New or rebuild
Should I send it to the local shop for rebuild with some upgraded parts or buy a new one? The quote right now is $1250.00 to have me take it to them and get a rebuild with "upgrades" I'm assuming upgrades mean premium parts.
This will be used in my 71 with a 402, both the engine and trans are the originals. The engine will have mild work at some point (375HP) range. Anyone here in/near Sacramento, CA that can do the work or perhaps I can even ship to someone? Or purchase new from you? Let me know thank you! |
Re: Th400 New or rebuild
Building a 100% new TH400 costs a small fortune.
A stock rebuilt TH400 will handle 375 hp. My base TH400 is $750, No core needed. Includes...... 4L80E Forward Hub (Stronger than a TH400 piece) Rollerized Output Dual Fed Direct Clutch 4L80E spirolock intermediate sprag retainer Sonnax Boost Valve & PR spring Pump gears Borg Warner hi energy forward & intermediate frictions Raybestos face grooved hi energy direct frictions New lo/reverse band All new bushings, seals & filter Stock rebuilt converter, $100. Upgrades if you plan on more power in the future.... 4L80E 34 element sprag & direct drum, $200. HD spirolock intermediate clutch snap ring, $16. High rate direct clutch return springs, $25. Not Trans Go junk! Reverse servo shim, $26. 190psi PR Spring These upgrades will allow for up to 600 hp. Above 600 hp, A billet Input shaft, Forward Clutch Hub & 215 psi PR spring are recommended. I do have some super low mileage Jaguar Cryo Treated input shafts living in 800hp trans brake cars......But with entry level Billet shafts costing around $200 now, Roll with billet if needed. PM me if interested. |
