While the TH400and TH350 transmissions may not be in production anymore, but they both still enjoy quite a life in the performance and racing communities. The shifters that came with these transmissions do not lend themselves well to precise shifting mechanics. In breaking down which shifter is best, we approached it from the perspectives of would you need to use it primarily for racing, the street, or if you need a budget option.

1. Lokar FM350BM - Lokar Floor Mount Automatic Transmission Shifters Automatic Shifter, GM, TH350, 16 in. Single Bend Chrome Stick, Original Brushed Mushroom Knob, Each Part Number: LOK-FM350BM (3).
2. Brand new b&m auto ratchet quicksilver shifter,black finish,universal 3 & 4 speed,12.23' shift lever length,compatible with gm th350,th400,700r4,200r4,4l60, 4l60e - 4l80e transmissions 5.0 out of 5 stars 5.

Most of these transmissions came in older muscle cars or trucks. If that is the case for you, the column and floor shifters that came in these cars can be woefully inaccurate. Getting something like a direct shift cable solution from someone like Lokar can certainly help them feel better, but if you want better shifts out of your TH350/TH400 these shifters will totally help you achieve that end.

Best TH400 and TH350 Shifter for the Track

What makes a great shifter for racing?

To shift from Park directly to Drive, depress the release button and then hold it down while moving the shifter lever, and the shifter lever will automatically stop in the Drive position. Once you release the button, the shifter lever can be moved into 2nd gear. You must depress the release button again to shift down into 1st gear.

• Neutral and reverse lockout
• Ratcheting

The last thing that you want to do is miss a gear. A ratcheting shifter that locks out reverse, neutral, and park will keep you from dropping your transmission on the track. They’ll also provide a much more consistent shift than a stock column or floor shifter. You’ll feel the next gear lock in almost like you are shifting a manual transmission.

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.

This is our Stage 1 TH350 build with a heavy duty K case core and using a reverse manual valve body with engine braking for rock-crawling or off-road use.

Stage 3 TH350 will add a billet 300M input shaft making it good for 800 HP. Typically at this power level we recommend a TH400. Please let us help you with selecting the unit that best suits your needs.
