Recommendation:
What can blow the budget
- Cracked case (replace: $800-$1,500)
- Damaged planetaries ($500-$1,200 HD billet)
- Failed input shaft ($600-$900 billet replacement)
- TCM failure (rare but $1,000+ if shop diagnoses)
- Wiring damage during R&R
Saving money tips
- Always do all filters (cheap insurance)
- Use TES-295 only (wrong fluid kills $5k rebuild)
- Replace converter at rebuild (cheaper than rebuild #2)
- Get the right stage kit (no underbuilding tuned trucks)
