As a car enthusiast, having a street sleeper that is a car faster than it appears to be can be fun. The  Pontiac G8 GT comes with many features that make it a fast car while maintaining its ability to throw people off course with its sedan appearance. Regardless of whether it has been a sleeper car, you can ramp it up with different modifications.

Many people overlook car transmission when upgrading their cars. The aftermath is usually calling a tow truck when they turn on the revamped engines. The transmission is basically anything between the wheels and the engine and transmits torque. A weak spot between the wheels and crankshaft is usually where the transmission fails.

Numerous mods can be done on the 6L80 transmission, making the car faster and more fun to ride. You can read more on the specifics of the 6L80 transmission here, https://reman-transmission.com/transmission-codes/?code=6L80. This article will look into some of these transmission supporting mods for your Pontiac G8 GT.

Tuning

You should note that your Pontiac G8 GT transmission does not operate in a vacuum. The transmission works in tandem with your engine. Therefore, the transmission and engine need to be tuned together as a package for each to perform optimally.

Tuning can range from reprogramming the control algorithms to completely replacing parts. The transmission tuning can involve the following methods:

  • Reprogramming (TCU remapping/ chip-tuning)
  • Quality tuning ( replacement of automatic transmission components)
  • Deep tuning

Some of the benefits of tuning will include:

  • Increased power and torque due to the relaxing of gearbox torque limiters
  • Quicker gear shifts
  • Smoother gear shifts
  • Faster reaction Tiptronic
  • There is better fuel economy due to reduced power loss through the drivetrain.
  • Improved off the line response and low speed
  • Elimination of excessive jolts and kick-downs

Synchs and Dogs

A dog engagement and a synchronizer system provide a swift and easy gear change. They are also mainly present in street transmissions. That notwithstanding, the synchronizer system applied in the gearbox engagement is not built for intense driving, making its durability questionable.

A good alternative is the Dog engagement, which performs louder and is more durable, especially in demanding conditions such as racing. The featuring of cogs and dogs attached to the slotted enables the upshifting of dog boxes with or without a clutch.

DCT Transmission

Many big players are currently upgrading to the dual-clutch transmission. The transmission replaces the three-foot pedal that has been believed to be a sign of performance over the years.

HOWEVER, a DCT transmission provides quicker shifts and eliminates the room for missed shifts. This is because the DCT transmissions are sequential. Therefore, if you are looking to maintain top speeds, it will serve you better if you aren’t missing shifts, irrespective of the efficiency of your gearbox. Also, it takes more time to use your left foot and shift your arm to change gears.

Straight Cut Gears

Transmission gears either have a helical tooth cut or a straight one. Helical gears perform very silently due to gradual contact between the gears due to the application. However, the gears encourage wear due to the teeth meshing at an angle with thrust forces on the bearings.

On the other hand, straight-cut gears are best used for racing applications. The gears are much louder, which may make them difficult for street driving. However, the gears are more durable since they are thicker. It would be best if you, therefore, considered adding straight-cut gears to your Pontiac.

Sequential Transmission

Manual transmissions can either be a sequential pattern or an H-pattern. H-pattern shifting is featured in the Pontiac and allows and allows gears to be changed by shifting to jumping to a specific gear. The pattern allows the easy change of gears.

On the other hand, the sequential transmission offers a super-fast gear shift where you can move the gear in descending or ascending order. The possibility of a miss-shit is low in the sequence but will occur if the selector is not engaged appropriately. This shifting mechanism and dog engagement will make the transition shift faster.

Transmission Modifications That Will Not Disappoint

It will help if you upgrade your transmission for the best performance of the Pontiac G8 GT, which comes with a GM 6L80 transmission. The modifications will give the car impressive and remarkable performance to ensure your car’s enthusiasm is satisfied.

Therefore, if you want your car to reach impressive speeds and give you high performance, the mods on your trans will go a long way toward achieving that. Give the mods a try and see how well the speed of your engine is boosted.
