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 for a 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 1 TH350 is reliable to over 500 HP/TQ. It’s a very tough unit. It has several key modifications that increase it’s strength. Increased line pressure and lube flow. Additional bushing area, close attention to bushing clearance, blueprinted pump assembly, select cores used, and other areas that our experience has shown other shops and builders are not paying attention to.
