Yes — 4Runners hold their value extremely well. A rebuilt transmission with lifetime warranty on a clean 4Runner is the right call.
Absolutely — off-road use introduces contaminants faster. Change ATF WS every 20,000–25,000 miles and inspect for metal particles.
Could be the rear transmission seal or the transfer case output seal. We'll diagnose — the transfer case seal is a common 4Runner issue that looks like a trans leak.
3–4 days.
The A750F is a solid unit. The key is fluid maintenance — contaminated fluid from off-road use kills transmissions faster than the terrain itself.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
