How much does it cost to rebuild a 350 turbo for 78 Chevy 4x4?

The cost to rebuild a 350 Turbo transmission (TH350) for a 1978 Chevy 4x4 can vary significantly depending on several factors:

* Condition of the transmission: A transmission that needs only a minor repair (e.g., a seal replacement) will be far cheaper than one requiring a complete overhaul with new clutches, bands, and other internal components. Severe damage, like broken shafts, will add substantially to the cost.

* Parts used: Using remanufactured parts will generally be cheaper than new parts. Using high-performance parts will be more expensive. The quality of the parts also matters – cheaper parts might not last as long.

* Labor costs: Labor rates vary drastically by geographic location and the shop's expertise. A specialized transmission shop will likely charge more than a general mechanic.

* Additional services: If you need additional services like a fluid cooler installation or a torque converter rebuild, that will increase the cost.

Rough Estimate:

Based on these variables, a reasonable estimate for a rebuild could range from $800 to $2500 or more. A basic rebuild with used/remanufactured parts and moderate labor costs might fall on the lower end. A complete rebuild with high-quality new parts and specialized labor could easily reach the higher end or even exceed it.

Recommendation:

To get an accurate estimate, it's crucial to:

1. Have a qualified transmission mechanic inspect the transmission. They can diagnose the problem and provide a detailed quote.

2. Get multiple quotes from different shops. This will allow you to compare prices and services.

3. Clearly specify the parts you want used (new, remanufactured, etc.).

Don't just rely on online estimates; an in-person inspection is essential for accurate pricing.
