A pickup based in Bushnell is about 50 miles from both Tampa and Orlando, so its transmission spends a lot of time in top gear on I-75. A heavy truck working the same corridor may still have a clutch pedal. Both get repaired at RDI Power’s shop at 1665 Donto Way in Brooksville, about 28 road miles from the middle of Bushnell, and both start the same way: a diagnosis that finds the cause before anyone talks about a rebuild.
I-75 cruising and the Bushnell commute: converter and overdrive wear
At steady highway speed, a modern automatic sits in its top gear with the torque converter clutch locked, which is the easiest work it does. The trouble spots are the transitions. A converter clutch that shudders as it applies feels like driving across rumble strips at light throttle and steady speed, and it shows up as slip on a scan tool. Worn fluid makes it worse, so a fluid change is sometimes the first step, but a converter that keeps shuddering needs more than fresh oil. We road test with the scan tool connected to see exactly when lockup happens and how much it slips.
Manual transmissions and clutches on Bushnell heavy trucks
Plenty of tractors and older pickups still shift by hand. A clutch that slips under load, chatters on takeoff, drags so the truck creeps with the pedal down, or makes the transmission grind going into gear is telling you something. On heavy trucks, clutch adjustment and the clutch brake matter as much as the disc itself, and a release bearing that has been run dry can take out more parts on its way. Our clutches page covers the repair in more detail.
Tuned Bushnell pickups and the transmission behind them
Adding power to a diesel pickup does not add strength to the transmission behind it. Clutch packs and converter clutches are sized for factory torque, and a tune that raises it can bring on slipping in high gears, flare on shifts and fluid that overheats under tow. When a tuned truck comes in with a shifting complaint, we check fluid condition, codes and slip data, then talk honestly about the options: a stronger rebuild, a different tune or both. Our engine tuning page covers the engine side of that conversation.
Limp mode between Bushnell and Brooksville
If the transmission drops into a fail-safe gear on I-75, get to the next exit if the truck will safely go there, or to the shoulder if it will not, and call. A technician can often scan the truck where it stopped and find whether the cause is a sensor, wiring or something inside the case. Low or burnt fluid means the truck should be towed, not driven, the rest of the way.
We work on the Ford 10R140, 6R140 and 5R110W, the Ram 68RFE and Aisin, the Allisons behind the Duramax, medium-duty Allisons in trucks and buses, and manual transmissions and clutches. Ford IDS and WiTECH give us dealer-level access to Ford and Ram transmission modules, and every job comes with photos in a digital inspection and a 3-year / 36,000-mile labor warranty.

Engine complaints often travel with shifting ones, so our Bushnell truck repair page may help, and the Brooksville transmission repair page describes the shop where the work happens.
