So my 02 Ford F250 water pump started leaking, and i replaced it. In doing so, i had to remove the radiator, in which required the removal of the transmission cooler lines. Upon finishing the replacement, i forgot to check the transmission fluid. my son drives my truck the next day and the transmission starts slipping. I check the fluid level and its not touching the dip stick. I add fluid,and all returns to normal except i have no low end torque, a definite slipping. RPM's have to build up to 2500 or so to move. had a guy look at it and he said fluid is burned, probably clutches. Now for my question, whats the mechanics thoughts on rebuild verses jasper replacment?

I have always rebuilt.

I'm thinking rebuild for costs savings, but it appears that there aren't many around rebuilding transmissions anymore.

I've heard the same recently (that replacing is better than rebuilding), but don't quote me on that. I'd price both out and see which is better price wise. Make sure if you go the rebuild route, that it is from a REPUTABLE transmission guy!

Depends on the builder. I damn sure wouldn't get anything from Jasper engines and transmission. They suck and most times you can buy a factory crate for the same money.
It's a long way from you but I know a guy...

A1 performance transmission. Upgrades everything that the factory didn't. I've spent countless hours researching parts and turning wrenches and close to $6k on my early 99 7.3 f250 over the past 3months from engine seals and parts,transmission parts,performance parts, lift,diagnostic software,etc. This project came about due to a trans issue from overheating and puking out all the trans fluid and snowballed downhill from there. I've learned quite a bit and talked with several people and retailers about the powertrokes. When my trans gives up the final ghost it'll be gone thru and rebuilt by a1 performance transmission in Georgia. Chris is a 4r100 guru. Price is close to $4k for him to do it himself(includes converter and everthing)but he'll ship you a trans if you want to install it yourself. I'll keep doing all my on engine work and diagnostics but my trans is going to him. RiffRaff diesel and dieselorings is your best places to call on 7.3 parts,etc. Customer service from both are oustanding. I'm fond of my old powerstroke and justified the finances to go towards it due to it having less than a 2 yrd old paintjob and exterior parts on it from being damaged in a tornado. Plus it's a workhorse without all the new fandangled electronics like the new diesels. Will be building a spare motor to have it ready to go in when this one goes out. Which hopefully isn't soon. By the way whichever route you take i would definitly put in a 6.0 trans cooler and aftermarket gauges(i like isspro ev2 series)when you vet the trans redone. Simple bolt in design like the factory 7.3 cooler but 3 times the size and just an idea of it's efficiency,my temps before would run about 170 -190 sometimes over 200. Now they run 130-140.

My nephew just had the transmission go out on an older F250 gas burner. He had it replaced, but from what I understand, even when you buy a "crate" transmission from Ford for the older models, it is a rebuilt transmission.

Just a thought,if you've got the time and willing to spend $200 you could go get 5gl bucket of atf fluid(mercon) a motorcraft filter(yours will have a long pickup on the filter),transmission funnel, about 10ft of 7/16 clear tubing(any kind) and change out the entire system and see exactly how bad the filter and magnet looks. Who knows you might buy you some more mileage. Any questions on how to do the complete flush there's very easy info to follow on the powerstroke forums.

I'm not a mechanic by any means but I do know a guy in Brewton that might could answer some of your questions and give you prices.

10-4, thanks for the ideas.

Most mechanics can change out transmissions, but most don't rebuild or not good at it. Find someone in a major city and have your vehicle towed if need be if you don't have a good shop nearby. Ask for city nearby and someone probably knows someone good there on here. I wouldn't just carry it anywhere they are guys really good at it.

I usually weigh price verses warranty, most transmissions nowadays I can get a new one from the dealer for less than it cost me to build it and the new one has a 100k mile nationwide warranty. There are exceptions non- electronic older transmissions can still be built for a reasonable price.

This is a 4R100 transmission. I have a guy that worked for ford for years that works for a different business now that is going to price it for me. I've known him a long time and he's a good mechanic. We're going to discuss the options.

If can get it to Theodore , see glen at transmission magician . He did mine about 4 years ago and still running strong.

Since we are on the subject, about what would be the cost of a rebuild vs. replace on an F150 instead of F250?

Call Adams Garage in Opp. Best in the transmission business, call 334-493-6436. Fast service also.

I sold a tranny to guy for his f250 about 6 months ago. He has always been a good customer so I tried to help him out all I could. I got him 3 prices on a rebuild. Then priced a kit. Then sold him a new one. I can't remember the numbers but I do remember the new trans around 1000.00 less than the shops price. All 3 shops would not build it back factory. All 3 would beef it up. To give any warranty.

Trans messed up in my Chevy, know this as a ford, rebuild was $3500 with 3 month warrenty, new was $5500 with 100,000 miles at the local dealer put a new in mine, forgot 2500hd diesel it was an Allison transmission

Do not biy a jasper is u want a reman i suggest ats mich better price and less trouble to deal with

HUH?????
