Tired of breaking 4L60E's?
Specializing in Racing Automatics, GM LSx crate engines, parts, and retrofits, Performance Engine Building and Installation, and complete musclecar service.
We have an excellent track record with our TH350's. Deep into the 10's without failure, they have proven to be a very tough unit and for a very reasonable price. We feel they are a very good choice in cars up to 600 HP/TQ but capable of up to 800 HP/TQ especially in lighter cars.
The limiting factor is the stock planetaries. There are aftermarket planets available to make them live at even higher power levels but we usually recommend a TH400 for a dedicated 600+ HP application. Our goal is to provide long term reliabilty.
Our base model TH350 has lived at over 600 HP reliably.
As with all Jake's Performance transmissions they include all new friction clutches, bands, steel plates, soft parts, filter, modulator (if applicable), as well as hydraulic upgrades, and other modifications depending on power level. All TH350 transmissions include a new pan.
Stage I TH350 is reliable to over 500 HP/TQ. It's a very tough unit and budget oriented.
Our Stage II TH350 includes all the features of the Street model plus a 36 element sprag and drum upgrade, special retaining ring on the sprag, upgraded red friction materials in the direct and intermediate clutch packs and a deep aluminum pan standard.
750 HP/TQ capable.
Valve Body Options with TH350's. Please pick an option and add it to your cart.
Deep Cast Aluminum Pan Option. Add to your cart if you want a deep cast aluminum pan on your transmission order.
Upgrades are available. 4340 or 300M input shafts, fully rollerized with lightweight parts for competition applications, low gearsets for heavy cars or truck applications.
Please Note:
$150 shipping within the cont. U.S. only from our location to a local freight terminal or business with a forklift or loading dock. Other shipping methods require you to call us for a quote.
